Perfecting technology of winter concreting of cast-in-situ columns
Authors: Imaykin D G , Ibragimov R A , Evstigneeva Yu V 
Published: December 2019

Abstract
The article deals with an analysis of the existing systems of the heating method of reinforced concrete structures. It is demonstrated that, concreting of rectangular columns, the area of angles is characterized by a lower concrete quality than in other areas, which causes extensive damage in indicated zones. To remove the existing limitations, the formwork design for concreting of cast-in-situ columns is offered in the article. It was established that during the removal of column formwork one can often observe palled angles with reinforcement uncovering. Corners are the most vulnerable parts under impact forces or static loads during the exploitation. Repair and restoration of the exterior view and protective properties of concrete in column corners often require using materials or repair methods, which increase the cost of construction. The reasons of concrete lower quality are in the incompact joints of formwork elements and the chilled temperature of concrete hardening. Furthermore, the reason is in low temperature in columns corners. It is the consequence of the deficiency of existing heating systems ignores the irregularity of heating proper emission of the heat and increased heat loss in the corners of the columns.
Modeling and studying basic parameters of tank sets in combined regasification
Authors: Osipova N N , Kuznezov S S , Rulev A V 
Published: December 2019

Abstract
This paper proposes switching tank sets to combined regasification so as to reduce the energy consumption in artificial regasification systems. To that end, a tank set must be equipped with a special valve to sustain a pressure of 0.135 MPa in vapor blankets. This valve will trigger alternating draft of liquid and vapor phases of liquefied petroleum gases so as to maximize the utilization of the natural evaporating capacity of feed tanks.
To make the proposed solution scientifically sound, the research team has developed a mathematical model of combined regasification of liquefied petroleum gases, which integrates the two basic periods of tank-set operation: natural regasification in the feed tank, and artificial gasification in the evaporator. In order to validate the proposed model, a pilot set was used for experimentation. The obtained experimental data correlate well with the numerical output of the proposed model, making it recommendable for engineering practice. Studies show that implementing combined regasification in liquefied gas tanks will considerably reduce the energy costs of evaporating gas, making the liquefied gas supply systems much more energy-efficient and cost-effective.

Authors: Korobova O A , Maksimenko L A , Solovyanova I Yu 
Published: December 2019

Abstract
The article presents the sequence of calculation of ground bases for deformations, taking into account their deformation anisotropy. The calculations were performed by the finite element method using the mathematical planning of the experiment. It is established that after determining the index of the deformation anisotropy of the soil, you can use the results of the numerical experiment and the tables of the coefficients of the soil anisotropy influence, calculate the sediment of the soil base and layers of different thickness by any of the currently existing methods, taking into account their deformation anisotropy. It was revealed that the nature of the deformation anisotropy of the studied soil types is different. With an increase in the compressive load, the values of α increase, and with an increase in α value, the values of the sediment of the foundations increase as well. Taking into account the natural anisotropy of soils makes it possible to more reasonably prescribe the dimensions of the base of the foundations and determine their draft, and in some cases obtain a noticeable economic effect.

Authors: Dolgih G V , Ignatov V F , Utkin V A 
Published: December 2019

Abstract
The article assesses the possibility of using ash and slag mixture for the construction of a road bed. To this end, the traditional and modern methods of calculation of road surfaces are analyzed, which allow establishing the parameters of strength and deformability that require experimental determination. Experimental determination of strength and deformability parameters is performed by laboratory tests. For the implementation of tests the authors make samples of ash and slag mixture of different density. During the experiments, the metal stamp is pressed into the model and the experimental dependences of the sediment on the pressure are determined. This makes it possible to calculate the California Bearing Ratio, the deformation modulus, and to establish the pressures at which the mixture of ash and slag operates under compaction or shear conditions. Mathematical models are developed to calculate the parameters of strength and deformability from the value of pressure.

Authors: Ter-Martirosyan A Z , Ermoshina L Yu 
Published: December 2019

AbstractModern construction is developing at enormous speed, which leads to the need for more in-depth study of the physical and mechanical properties of soils in general, and clay soils in particular, in order to make rational use of their natural properties in the construction and design of foundations, foundations and soil structures. In this regard, recently, special attention has been paid to the study of the rheological properties of soils. One of the main rheological parameters of the soil is its viscosity. To determine the coefficient of viscosity of the soil in this study, a simple shear device was used. An artificially created sandy loam consisting of fine quartz sand (60% by weight) and clay particles (40% by weight) was adopted as the test soil. In the course of the study, characteristic graphs of the dependence of tangential stresses on shear deformation at different test speeds were obtained. Also, taking the Newton equation as a basis, the average value of the soil viscosity coefficient was determined for each shear rate.

Published: December 2019

Abstract
Large underground mine workings of hydropower facilities created in complex engineering-geological and seismic conditions significantly differ from industrial underground facilities designed for different purpose in their construction, operation and operating conditions. This makes it extremely urgent to organize seismic-acoustic monitoring in order to ensure their safe and reliable operation and prediction of the status of the underground circuit. The solution of this problem requires the improvement of methods and techniques for field observations of the operation of underground structures during construction and operation. In this paper, we formulate the basic principles of the organization of seismic-acoustic monitoring of the rock mass state that contain mine workings. We propose system of seismic-acoustic monitoring of a complex of underground structures, for example, the underground circuit of the Rogun HPP, which is under construction. The paper presents the field observation technique using seismoacoustic methods: seismic transmission and profiling, seismic well logging, acoustic emission method for concrete and boreholes, dynamic response method for assessing the quality of concrete-rock contact, ultrasonic well logging, ultrasonic studies of rock samples and concrete structures. Effective qualitative and quantitative parameters have been determined, which make it possible to assess the degree of change in physical parameters in the internal parts of rock massifs that occurs under the influence of natural and technogenic factors. This is done in order to assess ultimate strain levels and to find indicators of the critical state of the geological environment in problem areas.

Authors: Izvekov Yu A , Torshina O A 
Published: December 2019

Abstract
This article describes mathematical modelling of reliability, safety and risk indicators related to load bearing structural elements. The number of this type of cranes used at a modern iron and steel enterprise constitutes more than half of the total number of cranes. Therefore, the concerned issue and the problems addressed in this case represent current interest. Due to the impossibility of conducting a laboratory or a full-scale experiment, a numerical experiment is conducted using model distribution. Benchmark data used for calculations and based on previous studies performed by the author and available statistical data about incidents and damages are systematized and proposed. Hypotheses about addition and multiplication of damages related to elements of the equipment under study are made. Modelling adequacy is observed when the experiment findings match with available data. Classification of incidents arising when metallurgical cranes are operated beyond the expiry of their warranty period is identified. These calculations and procedure develop the theory of structural risk analysis of complex technical systems and allow making correct engineering-related managerial decisions.
