A prediction model of ground vibration considering the local amplification of vibration
Authors: Zhao Hong , Zhou Ming , Yang Fulian , Dong Wenxiu 
Published: November 2020

Abstract
The ground environmental vibration caused by traffic load will attenuate monotonously with the increase of the distance from the load source. However, considering the complexity of stratum factors, the attenuation of ground vibration will have local amplification of ground vibration instead of monotonous attenuation. This article is based on RBF neural network. The method can predict the ground environment vibration of the local amplification phenomenon of the ground vibration. This paper selects the theoretical solution of the complex theoretical model to perform the fitting approximation and the numerical approximation with the measured discrete data. The results show that the numerical approximation is better. Since the RBF neural network does not require other neural network models to perform supervised learning training, the numerical convergence speed is also relatively fast.

Effect of Transverse Damage on Transverse Load Distribution of Bridge Side Beam under Moving Load
Authors: Du Wei Qiang 
Published: November 2020

Abstract
In order to study the variation of transverse load distribution of T-beam bridge with transverse damage under moving load. In this paper, nine kinds of working conditions are proposed for the possible failure modes and the different locations of the failure, and relevant finite element models are established. Through simulation, the lateral load distribution of middle beams under nine working conditions is obtained and compared with that under non-damage condition. The results show that the transverse load distribution capacity of T-beam bridge under moving load will be greatly affected after the transverse connection damage of the diaphragm beam occurs. When the location of transverse damage is different, the influence of T-beam bridge will be different.

Published: November 2020

Abstract
In the artificial stratum freezing method construction, the stratum temperature is an important basis for judging the thickness, strength and stability of the frozen wall. The temperature of the circulating return brine is an important indicator reflecting the state of heat exchange between low-temperature brine and the stratum. Due to the large number of temperature measurement points, long measurement distances, and relatively scattered positions in the freezing project, this paper uses a single-bus temperature measurement technology to develop a monitoring system based on high-performance microcontrollers and distributed digital temperature measurement cables on the hardware. Combined with LabVIEW software, the real-time collection and monitoring of temperature data is realized.
Stress Analysis of Extra-high Arch Dam with Closed Arch Grouting during Summer Constructions
Authors: Shi Li , Huang Peng , Zhang Ying , Di Shengjie 
Published: November 2020

Abstract
In this paper, the stress state of the summer arch grouting area of the extra-high arch dam is studied to determine how the summer arch grouting will affect the dam body, considering the dead weight, water pressure, temperature and other loads. The results show that the most unfavourable working case after considering the dead weight and water pressure of the arch dam is that no water storage in the winter. The upstream arch direction should consider a certain amount of tensile stress superimposed by the dead weight and water pressure. The high stress of the surface concrete in the closed arch grouting area in summer may cause the strength of the transverse joint to reopen after grouting. After the transverse joint pulled apart, the arch stress in other parts is released.
A three-dimensional limit equilibrium method for analysing the basal upheaval stability of deep slender foundation pits
Authors: Wang Chenghua , Li Yajie 
Published: November 2020

Abstract
Deep slender foundation pits, which are of small plane dimensions and deep retaining structures, have been increasingly used in engineering practice. Spatial effects of this type of foundation pits are obvious, but the existing stability analysis methods are not suitable for such deep foundation pits. Therefore, three-dimensional basal upheaval stability analysis methods considering the spatial effect are badly needed. On basis of former tests and numerical solutions, a new model of upheaval failure for deep slender foundation pits was suggested by application of the limit equilibrium technique for entire foundation pits, considering the influences of spatial effects of the retaining structures. A global factor of safety against upheaval instability was defined and the applicability of the method was demonstrated with some parametric analyses.

Published: November 2020

Abstract
The stability of foundation pit slopes is a key concern during the construction of foundation pits. The deformation and instability of slopes will pose a major threat to the safety of foundation pits construction. Based on the foundation pit project of Shenzhen Dapeng People’s Hospital, this study uses DJI phantom 4 RTK drone to collect oblique photography data of the foundation pit in different periods, reconstructs high-precision 3D virtual models through the Bentley ContextCapture software and generates the Digital Surface Model (DSM) data. The model quality report shows that the accuracy of the three-dimensional model is better than 5 cm, up to about 1 cm. Spatial analysis of DSM data in different periods using ArcGIS can obtain the deformation of the foundation pit slopes. This method can also be used for the calculation of earthwork excavation of the foundation pit, which can effectively reduce the field workload of traditional earthwork surveys.

Study on the penetration process of torpedo anchor into layer soils
Authors: Li Huanhuan , Li Gang , Zhang Jinli 
Published: November 2020

Abstract
Wing torpedo anchor is a new type of gravity anchor which is installed by self weight and anchored by gravity and seabed resistance. Based on the T98 torpedo anchor, the penetration process of torpedo anchor in layer soils is numerically simulated, and the change laws of penetration resistance, acceleration, velocity and penetration energy with depth is analyzed. The results showed that the end resistance and the friction resistance broke at the interface of soil layers, and the friction resistance increased with increasing of depth, while the end resistance first increased and then decreased. With the increasing of depth, the acceleration increased and the velocity decreased. In the early stage of penetration, the work is mainly done by the end resistance, whereas the work is mainly done by the side friction resistance in the later stage, suggesting that the side friction resistance consumed more anchor energy than the end resistance.

Abstract
This paper focuses on the application of Satellite Navigation Positioning System (such as GPS and BeiDou Navigation Satellite System) and InSAR technology in healthy monitoring in civil engineering. Considering the high cost of Satellite Positioning measurement and blind spot of InSAR measurement, it is reasonable to combine both technologies for accomplishing regionally area and focused points monitoring. During the study, the control network points were positioned with GPS measurement technique and height differences were supported with precise levelling measurements. As the result of measurement campaigns, the height differences were determined from the GPS measurements and InSAR measurements respectively. Later on, deformation analysis using the height differences according to provided data from the GPS and the data from the InSAR system were carried out separately. The comparison between GPS and InSAR results will be shown in the paper.
