Published: October 2022

Routine in-situ and laboratory investigations carried out for the basic design failed to provide reliable values for compressibility and consolidation parameters of soft clay layers at the site of a terminal to be built in Santos. A pilot embankment was designed and built divided in three equal areas, two with wick drains in a square mesh at spacings of 1.2 m and 2.4 m respectively and one with no drain. The basic working hypothesis adopted by the authors was that, in the field, primary and secondary consolidation occur simultaneously. High quality standard and special (long term and relaxation) oedometer tests provided reliable values of Cc , Cr and σ’p and the OCR value of 2.1 as equivalent to the end of secondary consolidation allowing to estimate the total primary and secondary compressions of one of the most compressible layers (layer 6). No of the shelf tool is available to backanalyze the measured compression of a soft clay layer based on the adopted hypothesis. The first tool tested, the ε vs. log(σ’v) Bjerrum type abacus with lines of equal values built from the oedometer tests results, proved to be non applicable. The second tool tested, the same type of abacus extrapolated from the first one for the field conditions through Taylor and Merchant’s theory also proved to be non applicable. Both the third tool tested, the fitting of a theoretical Taylor and Merchant type curve to the measured compression curve in the area with no drain and the fourth tool tested, the fitting of a theoretical curve obtained through a method tailored by the authors designated “Primary Barron + secondary pseudo Taylor and Merchant” to the measured compression curves in the areas with wickdrains proved to provide excellent conformity of the theoretical and measured curves. The cv and ch field values thus obtained are of the same order of magnitude as the laboratory values and show the same trend to decrease when the effective stress increases, contradicting the current creed based on backanalysis through Asaoka’s method, i.e. considering that secondary consolidation only starts after primary consolidations ends, that field cv and ch values are commonly 10 to 100 times higher than laboratory values. Based on their results the authors conclude that the excellent conformity of the theoretical and the measured curves obtained with the working hypothesis they adopted, the results of the laboratory tests they performed and the tools they used for the back-analysis, leads to the conclusion that the working hypothesis, the laboratory tests and the tools proved to be very efficient and trustworthy in leading to reliable compressibility and consolidation parameters of the soft clay, and will be equally efficient and trustworthy when used for the final design of the improvement of the foundation soft clay layer
Behaviour of Three Test Embankments Taken to Failure on Soft Clay
Authors: Almeida M.S.S. , Oliveira H.M. , Dias D. , Deotti L.O.G.
Published: October 2022

This article compares and analyses the behaviour of three test embankments. The soil foundation consisted of normally consolidated clay overlain by a thick sand surface layer. The embankments were rapidly constructed until failure, which occurred after approximately 50 days. Two of the embankments were reinforced, one including prefabricated vertical drains (PVD), while the third had neither reinforcement nor PVDs. The two reinforced embankments presented similar net embankment heights (fill thickness minus average settlement) at failure, owing to the similarity in the undrained strength values of the two clay layers. The test embankment with PVDs showed that this drainage feature improved overall behaviour but the benefit was less than suggested in the literature, owing to the low coefficient of consolidation of the normally consolidated clay, rapid construction and drain disturbance effects. Numerical analyses of the test embankment with PVDs showed good overall agreement between measured and computed values and confirmed overall field observations. The embankment without reinforcement and PVDs reached a greater embankment height than the two reinforced embankments, owing to its greater clay strength.

Published: October 2022

The supporting mechanism for overburden strata supported by artificial pillars is a complex issue. A calculation method for the size optimization of an artificial pillar in a deep area based on Protodyakonov’s ground pressure theory was proposed. In this study, the sizes of artificial pillars in different mining sections in a specific mine were calculated. In addition, the stability of these artificial pillars and the supporting effect for the overburden strata in the gob areas were studied. First, the size parameters of the artificial pillars in different mining sections were determined. Second, the supporting mechanism and stability of the artificial pillars were studied by means of numerical calculation. A regular pattern in which a larger gob area span corresponds to greater settlement of the overburden strata were found. The overburden strata are stable based on the distribution condition of the plastic zone. Finally, field measurements were performed, revealing continuous increases in both the pressure borne by the artificial pillars in two middle sections at the primary stage and the settlement displacement of the overburden strata. After reaching a certain level, the increasing trend slowed and finally plateaued. The maximum stress of the artificial pillar at a depth of -430 m was 0.78 MPa, and its maximum relative settlement of the overburden strata was 4.4mm. Similarly, the maximum stress of the artificial pillar at a depth of -460 m was 0.43 MPa, and its maximum relative settlement of the overburden strata was 2.7 mm. The study results showed that the designed artificial pillars are capable of supporting the overburden strata with good stability in the mining process and can effectively prevent the destruction of surrounding rocks and overburden strata in the gob area for the purpose of supporting the mine.
Influence of the Test Specimen Diameter on the Measurement of Electrical Resistivity in Sands by Using Laboratory Devices
Authors: Pregnolato M.C. , Giacheti H.L. , Peixoto A.S.P.
Published: October 2022

Electrical resistivity tests have long been used in geo-environmental site characterization because they provide qualitative data to identify the presence of contaminants in soil. The measurement of soil electrical resistivity is affected by many intervening factors, which are usually studied separately in the laboratory and are important to ensure the correct interpretation of in situ test data. This paper presents the evaluation of the influence of the diameter of test specimens on electrical resistivity measurements of a particulate medium in the laboratory, using two different techniques, copper plates and a resistivity probe. The data were discussed considering Archie’s Law, and it indicates that the geometry of test specimen has a greater effect than the measurement technique. The larger test specimen allows more current pathways for electron propagation because electric current travels along the path of least resistance to the passage of electrons. The findings from this research can be used to guide a laboratory test investigation and its data interpretation.
Data Extrapolation Method for The Dynamic Increasing Energy Test: SEM-CASE
Authors: Alves E.C. , Sales M.M. , Viana P.M.F.
Published: October 2022

The dynamic increasing energy test has been widely used in pile load tests in Brazil in recent years. However, the ultimate strength of the single-foundation system is not mobilized in most of the tests because of various factors. In some cases, the equipment available cannot attain the necessary kinetic energy, or the structural element presents initial imperfections/ruptures. In this study, the authors present a method for extrapolating the mobilized static resistance vs. maximum displacement curve, which is obtained using the dynamic increasing energy test (DIET). Using the force and velocity signals collected by the PDA (Pile Driving Analyzer) system, it is possible to calculate the resistance and displacement by applying the Simplified CASE Method. An extrapolation method, the Simplified Extrapolation Method of the CASE Method (SEM-CASE), is presented based on the results of twenty-one precast concrete pile load tests that have been carried out in different soils. The estimated values of the ultimate complementary energy and ultimate strength were very close to the measured values in the presented load tests.
Abscess of the piriformis muscle in a 14-year old boy - a transrectal drainage method under transabdominal ultrasound guidance
Authors: Szymak Katarzyna , Puliński Michał , Choiński Wojciech , Szostawicki Michał
Published: October 2022

Introduction

Sciatica is a common reason for a medical consultation throughout the population. Piriformis pyomyositis is a rare cause of these symptoms. Its probable etiology is transient bacteraemia co-existing temporarily with a muscle injury.

Aim

The aim of the study is to present a method for treating a piriformis muscle abscess with transabdominal ultrasound-guided transrectal drainage.

Case study

A 14-year old boy, previously healthy, was admitted with symptoms of sciatica that appeared after intense physical exertion. Laboratory tests revealed elevated inflammatory parameters and positive blood culture results indicating Staphylococcus aureus. Antibiotic therapy was implemented. MRI of the small pelvis revealed a forming abscess of the right piriformis muscle. On day 6 of the antibiotic therapy, in the absence of improvement, it was decided to perform transrectal drainage under ultrasound guidance. Clinical improvement was achieved, and the inflammatory parameters decreased.

Results and discussion

Co-existence of sciatica symptoms and signs of an inflammatory condition should prompt the consideration of piriformis pyomyositis. The mainstay of treatment for piriformis pyomyositis is antibiotic therapy. The abscess formation reduces its effectiveness, which necessitates surgical intervention. The authors present the application of transrectal drainage under transabdominal ultrasound guidance as the shortest route of abscess evacuation.

Conclusions

Transrectal drainage of piriformis pyomyositis is an effective and safe method. Concomitant use of ultrasound scans reduces the patient’s exposure to ionising radiation. However, the widespread use of this method requires more in-depth research and broadened experience.

A Novel Psychopathological Model Explains the Pathogenesis of Gastric Ulcers
Authors: Xin Min Dong Simon
Published: October 2022

The first detailed description of the morphology of gastric ulcer was reported ~230 years ago, but the mechanism has yet to be elucidated. Moreover, peptic ulcers, including duodenal and gastric ulcers, are currently considered an infectious disease caused by Helicobacter pylori, but how the infection leads to ulceration remains elusive. To address these challenges, a recently published Complex Causal Relationship was applied to analyze the existing data. Peptic ulcers were identified as a psychosomatic disease triggered by psychological stress, where Helicobacter pylori plays a secondary role in only the late phase of the disease. This etiology explained all the characteristics and observations/phenomena of peptic ulcers in a series of 6 articles. This second article focused on the pathogenesis of gastric ulcers. Based on hereditary predisposition, the accumulation of past life experiences incurs the formation of a negative lifeview. Consequently, the individual tends to negatively evaluate themselves or current life events, leading to acute psychological stress. The psychological stress triggers the release of aberrant neurotransmitters in the central nervous system, which in turn cause the transmission of pathogenic nerve impulses to the stomach, resulting in a ‘pre-ulcer lesion’ in the gastric wall and eventually, gastric ulcer. This psychopathological model elucidated 12 characteristics and 24 observations/phenomena of gastric ulcer, along with the roles of gastric acid, Helicobacter pylori, and NSAIDs. The effectiveness suggests that theoretical research and empirical study are equally important in medical explorations, and the guiding roles of philosophy are indispensable for the major progress of life science and medicine.
