Motornyj M. Forecasting of Finness of Wallplates in Deep Elaborations of Limited Sizes in Plan

The elaborations of limited sizes. The stability forecasting of vertical walls of limited sizes elaborations in plan. Experimental and theoretical methods. Apparatus: centrifugal machine and polarizaited optical installation, measuring apparatus. t is determined the forms of failured surfaces of vertical walls. It is defined the quantitive and quality scheme of tensions distribution around and in the foundation of deep elaborations and determined extreme length of elaboration with the it's gi en deepness and physico-mechanical it's given deepness and physico-mechanical characteristics of soil. Are developed the methodics of extreme length calculation of elaboration, extreme distances between antilandslide supporting constructions and is d termined the length of "bay" in constructions and is determined the length of "bay" in reconstruction process and strengthening of foundation. Economical effect - 200'000 grn. Field application - foundation engineering.
