Effect of temperature on the dynamic parameters of silty clay in a seasonally frozen region.

ABSTRACT: The effect of temperature on the dynamic parameters of silty clay in a seasonally frozen region was assessed using a GDS dynamic triaxial test system. The strength parameters, dynamic elastic modulus, damping ratio, and other dynamic parameters of the soil samples were analyzed under different temperature conditions. The results demonstrated that the shear strength parameters (internal friction angle and cohesion) of the silty clay under a dynamic load increased significantly with decreasing temperature, and the internal friction angle increased sharply below 0 °C. The dynamic elastic modulus increased as the temperature decreased and changed significantly in the ice-water phase change region. The slope of the dynamic stress-strain curve of the soil sample increased significantly with decr
