Prediction of soil collapse from trench soaking test data

Abstract

Results are presented for long-term full-scale field soaking of test trenches in the Ukraine and in the Rostov Region, for determination of the type of collapsibility soil conditions and the possible soil collapse in accordance with the SNiP 2.02.01-83 Norms. The relation between these results and the soaking regime is shown: water feed rate, number of drainage holes, soaking periodicity, engineering-geologic characteristics of the soils masses, presence and depth of occurrence of aquicludes, etc., which must be taken into account for soil collapse prediction.
