The paper discusses methods for the numerical simulation of the stress- strain state needed to evaluate the different boundary conditions of technical condition of long exploited surround impervious geotextile cover height adjustable fins . After a long period of operation of hydraulic structures continue to operate without routine repairs necessary to make the technical reconstruction of structures on the basis of innovation , as well as the previously proven technology of repair. The simulation result is characterized by the presence of non-hazardous for coverage of total movements , which shows the presence of a large margin of safety cover . It was also made ​​modeling the formation of various defects, namely the most dangerous - subsidence of the underlying soil. Education deflection along the length of coverage shown in the orthographic total displacement of the drawdown of the subsoil . Was numerically simulated work covering the load of its own weight and volumetric filling the cells of soil under different parameters . One of the pressing problems at present in the field of security for a long time operated water conveyance structures is the correct assessment of the residual life .

Keywords: waterworks, water-conducting structures, numerical simulation, the stress-strain state
