Flow Deformation of Liquefied Sand Under Constant Shear Load and Prediction of Flow Slide of Infinite Slope
This paper is intended to evaluate the behavior of saturated sand and sloped ground subjected to flow failure with seepage of pore water in the ground after earthquake. Triaxial compression tests of sand with constant deviator stress but changing pore pressure and volume of the specimens were conducted in this study. It was revealed that the relation between the volume change and the amount of shear strain during deformation depended on the initial density of the sand but it did not depend much on shear stress and initial confining stress levels. Based on test results and numerical analysis of the seepage of pore water in liquefied ground, a methodology was proposed to predict the deformation of inclined ground due to liquefaction.
