Abstract: Unconfined uniaxial compressive tests were performed to study the influence of cryostructure on frozen clay's behavior, such as strain-stress,compressive strength,and failure characteristics,at temperatures varying from -10 to -2℃ and strain rates varying from 1.0×10-5 to 1.0×10-3 s-1.Artificial samples were prepared of three types:(1) integral structure,(2) laminar structure,and (3) reticular structure.The impact of temperature,strain rate,and cryostructure on the mechanical properties is discussed.In general,frozen clay with various cryostructures shows strain-softening behavior in the range of testing temperatures and strain rates.For frozen clay of different cryostructures,the ultimate compressive strength increases with increasing strain rate and decreasing temperature.Under the same testing conditions,the ultimate compressive strengths from high to low are in integral samples,laminar samples,and reticular samples.Failure strain of frozen clay generally increases with increasing temperature and does not indicate any correlation with cryostructure or strain rate. The failure mode of integral and reticular samples was shear failure,while laminar samples showed tensile failure.

Key words: frozen clay, cryostructure, strain-stress relationship, ultimate compressive strength, failure strain
