Abstract

In order to study the liquefaction phenomena of silty sand, saturated specimens prepared in the laboratory according to the dry unit weight of undisturbed samples are used to examine the cyclic shear resistance, pore pressure and residual shear strain developed in these specimens under cyclic loading. These tests are accomplished with a cyclic simple shear test apparatus developed in Nanjing Hydraulic Research Institute. Based on results of these tests expressions of cyclic shear resistance, pore pressure, dynamic shear modulus and residual shear strain as functions of number of cycles, consolidation pressure, initial and cyclic shear stress etc. have been developed.

Pore Pressure in Silty Sand under Cyclic Shear

St. Louis, Missouri

In order to study the liquefaction phenomena of silty sand, saturated specimens prepared in the laboratory according to the dry unit weight of undisturbed samples are used to examine the cyclic shear resistance, pore pressure and residual shear strain developed in these specimens under cyclic loading. These tests are accomplished with a cyclic simple shear test apparatus developed in Nanjing Hydraulic Research Institute. Based on results of these tests expressions of cyclic shear resistance, pore pressure, dynamic shear modulus and residual shear strain as functions of number of cycles, consolidation pressure, initial and cyclic shear stress etc. have been developed.
