Critical state of soil
WebThe critical state soil mechanics (CSSM) concept is based on the observation that when soils are continuously distorted they trend towards and eventually reach a “critical state” … WebJul 12, 2024 · Correlations considering peak effective friction angle, undrained shear strength ratio and coefficient of earth pressure at rest with Atterberg limits are presented. Besides, critical state soil mechanics parameters were interpreted by correlating them with the plasticity index and the undrained strength ratio for normal consolidated soils.
