摘要

A method for investigation of state of enclosing structures in interaction with earth half-space on basis of methodology of calculation of elastic half-space with use of the moment scheme of the finite element method in geometric and physical nonlinearity at which one solves problems with use of criterion of stability on basis of extended Mises plasticity criterion with Mohr-Coulomb strength condition with use of set of respective models of earth foundation with account of real behavior of earths. After that one solves the stability problem in relations of plastic flow theory in increments with correction using changes in calculation of stress tensor for elastic-plastic material of engineering structures for most complete account of interaction specificity of enclosing structures and earth half-space.
