Abstract

Analysis and interpretation of flow and instability of sloping soil masses due to rainfall are made using triaxial compression test results. In this study, anisotropically consolidated undrained triaxial compression tests are carried out on two soils, Omigawa silty sand and Jamuna river silty sand. The degree of anisotropic consolidation is defined by K_c = σ_3c'/σ_1c', where σ_3c' and σ_1c' are the lateral and axial stresses achieved after consolidation, respectively. The flow characteristics of the soils are examined in several manners in terms of contractive and dilative behaviours, with respect to the consolidation line, steady state line, phase transformation line and initial dividing line. The residual strength is evaluated with respect to the initial state ratio. Finally, the method for the evaluation of flow susceptibility of sloping soil masses is discussed within the context of the interpreted test results.
