RESEARCH OF INFLUENCE OF THE ZONE OF THE INCREASED FILTRATION ON RELIABILITY OF THE STORE OF LIQUID INDUSTRIAL WASTES

Nadezhda Kalashnik

Abstract

The geo fluid mechanical model of the natural and technical system "the store-the protecting construction-the geological basis" which in the program PLAXIS complex has been realized in a computer 3D model has been developed for a research and assessment of reliability of the store of liquid industrial wastes. For each component of model it was set, taking into account basic data, the corresponding mechanism of deformation: elastic-plastic, elastic and viscous-plastic, filtration consolidation. As the changing influencing parameters have been accepted: levels of filling of the store, taking into account industrial and flood waters, coupling and the angle of internal friction of soil and also the sizes of a zone and speed of water filtration. Multiple parametrical modeling of the store on the basis of which results features of influence of geometrical and hydrodynamic characteristics of a zone of the increased filtration, taking into account considerable variability of the main deformation properties of soil of the protecting construction, on reliability of the store are established is executed. Model dependences of reliability of the store of liquid industrial wastes on mechanical durability and filtration stability of the protecting construction are revealed.
