Comparative assessment of the calculation of the sediment base of foundations by the SP method and the method of NRU "Geotechnika" MGSU and their analysis

Abstract

The article provides a comparative assessment of methods for calculating the sediment of foundations of finite width with and without taking into account the horizontal movements of layers, as well as taking into account the self-weight of layers. As a calculation, to estimate the stress state of the base, the Flemann formulas are used (the plane problem), which allow us to determine the stress components σx, σz, τxz, as well as the average stress σm = (σxp + σzp)(1 + ν)/3, depending on the load intensity p = const acting on the surface of the half-space along the strip b = 2a. In addition, this article provides formulas for determining the surface precipitation of a linearly deformable half-space S(x, 0) = f(E, ν, b = 2a).
