MA Chong-wu, LIU Zhong-yu, TIAN Jun. Horizontal displacements in infinite slopes of cohesive soil due to raise of groundwater table[J]. 2008, 29(5).DOI:
Based on the Mohr-Coulomb failure criterion and an associative plastic flow rule in the plane strain regime
an elastoplastic analysis is presented for the deformation in an infinite slope of cohesive soil with the model of translational slide due to the raise of groundwater table. And an attempt is made to establish a relationship between the horizontal displacements developed within a slope before failure and the safety factors. The numerical results illustrate that
as the groundwater table rises
the initial state of stress and the shear strength of soil have an important influence on the thickness of plastic zone
the plastic strains and the horizontal displacements before failure.
