THE PERFECTION OF A METHOD OF ANALYTICAL ACCURATE DEFINITION OF PHYSIC-AND-MECHANICAL CHARACTERISTICS OF ROCKY AND NOT ROCKY BASES OF HYDROTECHNICAL ERECTIONS ON THE BASIS OF FINITE ELEMENT MODELS WITH THE NATURE DATA TAKEN INTO ACCOUNT

Abstract


Moscow Owing to the various reasons, the real physic-and-mechanical characteristics of soil of the bases of hydraulic engineering structural systems can differ from design preconditions. The technique of settlement specification of the actual physic-and-mechanical characteristics of the rocky and not rocky bases of hydraulic engineering structural systems is offered. This is done on the basis of finite element models of the system "erection - basis" with taking into account natural supervisions over settling of erections. Examples of the application of the developed technique, concerning the bases of sections of the concrete dam of Boguchany hydroelectric power station and the water intake of the Zagorsk GAES-2 are given.
