PRACTICAL METHODS OF THE LIMITED CONDITIONS ANALYSYS OF THE FOUNDATIONS AND THE BASES
Methods of limiting conditions analysis of the bases, the foundations and the ground masses, based on the the mixed problem solution of the theory of elasticity and plasticity are considered. Problems of numerical realization of algorithms of such methods nave been analyzed. The information about features of numerical methods realization of the limited conditions analysis by the step-by-step method considering the structure destruction scheme in the computer complex «Nonlinear Polyfem». The essential Puasson's coefficient influence on the solution of the elastic and plastic problem. The methods numerical realization is illustrated by examples of calculation of the wall landfall and foundations, the LPT Recommendations of the algorithms elaboration based on the solution of an elastic-plastic problem, with application of the relaxation factor providing the group transition of final elements in limited conditions and allowing to avoid of the machine cycling.
