This paper presents the complex analysis of diverse field loading tests of four with diameter 600 mm CFA bored piles. Four static compression pile (by ASTM D1143) loading tests were carried out on the construction site. Static loading tests applied load to a deep-foundation element gradually for measuring foundation settlement. This test is used to measure the axial ...

The work is devoted to a comprehensive study of the bases and foundations of electric furnaces No. 61 and 63 of the melting shop of the Aksu ferroalloy plant. Engineering-geological and hydrogeological surveys of souls, geophysical work, as well as studies of the technical condition of existing foundations were carried out. Based on the conducted comprehensive scientific and ...

The problem of the action on the surface of a circular cylindrical cavity located in an elastic half-space (array) uniformly moving along its forming normal and twisting loads is solved. Dynamic equations of elasticity theory are used to describe the motion of the array. On the basis of the obtained solution, the stress-strain state of the Earth’s surface is investigated ...

Sand-rubber mixture (SRM) is widely considered as an energy-dissipating layer for vibration mitigation in soils. The present study is focused on using the SRM as an energy dissipation layer below building foundation referred to as the Geotechnical Seismic Isolation layer (GSI) which acts as a buffer to incoming vibrations. Geosynthetic reinforcement is included in the ...

Pavlodar is one of the main industrial regions of Kazakhstan, with a historically formed territorial and production complex, which is an important part of the national wealth of our country. Increasing volumes of construction of all forms of ownership of this city predetermine further increase of engineering design and survey works. However long-term observations show that ...

The temperature effects on foundations and structures. The results of calculations of ground bases and structures on temperature influences and loads are given. Conclusions on the obtained results with suggested recommendations are also made in work.

Three-dimensional finite element analysis has been widely used in foundation design. For the efficiency of computations, simplified analysis treating the soils by series of springs were suggested in many design practice. For piled raft foundation, the coefficients of subgrade reactions and the pile stiffness are thus important to the design analysis. This paper intends ...

The paper discusses the features of the implementation of a digital decision-making platform for evaluating educational content as part of a stakeholder-driven digital educational ecosystem. The authors propose a methodology of business process digitalization that considers a three-stage quality evaluation of educational resources regarding their content, as in traditional ...

The aim of this work is to study the effect of irradiation with heavy Xe22+ ions with energies of 165 MeV, 200 MeV, and 230 MeV on the change in the optical properties of ZrO2 ceramic. The choice of ion energies, as well as irradiation fluences of 1013-1014 ion/cm2 , is primarily due to the possibility of simulating radiation damage in ceramics that occurs when overlapping ...

In this paper, we present the results of liquid low-level radioactive wastes (LLLRW) treatment by direct contact membrane distillation (DCMD) using polyethylene terephthalate (PET) track-etched membranes (TeMs). PET TeMs were modified by styrene and triethoxyvinylsilane (TEVS) using UV-induced grafting. Modification led to increase in the contact angle to 99° of PET TeMs (pore ...
