This article addresses the problem of slope stability from two complementary perspectives. On the one hand, it considers practical issues related to improving the efficiency of construction on subsidence soils. On the other hand, since traditional experimental and theoretical methods proved insufficient, it was necessary to develop new methodological tools for solving this class of problems. A method is developed for calculating slope stability without predefining the shape of the failure surface, using the equations of deformation mechanics for a weighty soil massif under different formulations of the limit-equilibrium condition. The study extends the traditional approach by explicitly incorporating the Coulomb–Mohr limit-equilibrium condition within the deformation theory of plasticity. The finite element method is adopted as the general numerical tool for obtaining the parameters describing the behavior of the structure–soil system. Numerical analysis of the slope-retaining wall interaction shows that the most critical mechanism is the development of maximum horizontal displacements near the retaining walls, caused by shear deformation.
The paper investigates the influence of rational displacement of boundary conditions on the results of topological optimization of structures. It is shown that the traditional approach, which assumes a fixed position of loads and supports, may not consider a significant potential for improving the optimality criterion...

The paper focuses on the effect of the vertical ground acceleration component on slope stability. The proposed stability method is based on Newmark’s sliding block concept, which provides an intuitive indicator of slope stability. Contrary to the original Newmark method, both components of excitations, tangent and no...

The classical Melan equation modeling suspension bridges is considered. We first study the explicit expression and global properties of the analytical solution for the simplified ``less stiff''model, based on which we derive an a priori estimate for the original classical Melan equation and establish, under an explicit...
Besides the strength criterion, steel structures must also meet the deformation criterion, which in some cases may be critical. Excessive deformation of the structure may lead to additional loads and improper operation of the installed equipment. The most common practice in steel structure design involves using the fin...

A method for using simple isothermal diagrams to study the crisis-strain state of concrete under regime-induced thermal-power loading and forced deformation is proposed. The methodological foundations of the study are built on a clear distinction between the concepts of strain additivity and loading non-commutativity...

An analytical model is proposed to investigate the kinematic response of a single endbearing pile in partially treated soil under vertical P-waves. Region-matching method is adopted to divide the physical domain of the soil-pile system into three parts. The total vertical displacement of the system is assumed to be the...
