Abstract
As part of a long-term study to evaluate dynamic properties of frozen soils under simulated earthquake and low frequency loading conditions, cyclic triaxial tests were performed on laboratory prepared samples of ice and frozen clay. The cyclic triaxial test setup consists of four basic components: (1) an MTS electrohydraulic closed loop test system which applies a cyclic deviator stress to the sample, (2) a triaxial cell which contains the sample and noncirculating coolant, (3) a refrigeration unit and cold bath which circulates the coolant around the triaxial cell, (4) output recording devices to monitor the load (stress) and displacement (strain) of the sample during the test.
