Abstract

Cyclic torsional and triaxial tests of saturated sand under Ko conditions were conducted in order to examine the change of total lateral stress in the following cases: during the build-up of excess pore water pressure under undrained cyclic shear, and during the one-dimensional compression, expansion and recompression due to dissipation and redistribution of excess pore water pressure following undrained cyclic shear. As a result, a simplified method is proposed to estimate the changes of the total and effective lateral stresses in saturated sand with changing excess pore water pressure after undrained cyclic loading in Ko conditions.

Total Stress Change During Cyclic Loading under Ko Conditions

St. Louis, Missouri

Cyclic torsional and triaxial tests of saturated sand under Ko conditions were conducted in order to examine the change of total lateral stress in the following cases: during the build-up of excess pore water pressure under undrained cyclic shear, and during the one-dimensional compression, expansion and recompression due to dissipation and redistribution of excess pore water pressure following undrained cyclic shear.
