RESEARCH ON FORECASTING THE TIME OF OCCURRENCE OF SLOPE FAILURE

Abstract

Full-scale experiments have shown that slope surface strain measurement is the most promising means of forecasting the time of slope failure. For this purpose, creep-rupture characteristics of soil must be known. The author proposes a method of forecasting the time of occurrence of slope failure, i.e., rough estimation from steady-state strain rate in the secondary creep range and precise estimation from optional strain rate in the tertiary creep range.
