Temperature‐Independent Relationships for Frozen Soils
Publication: Journal of Cold Regions Engineering
Volume 6, Issue 1
Abstract
Constant strain‐rate and creep tests were conducted in uniaxial compression on saturated samples of six fine‐grained frozen soils at temperatures between and From the test results, a number of relationships were developed that do not include temperature as an explicit parameter. The constant strain‐rate test results yielded relationships between peak strength and yield strength and also between peak strength and residual strength. From the creep test results, relationships between secondary strain rate and time required to reach the secondary creep stage were developed. Furthermore, separate relationships between the relative creep load, defined as the creep stress‐to‐peak strength ratio, and the secondary strain rate, initial strain, and initial strain rate were developed. The creep behavior of a fine‐grained frozen soil at various temperatures is found to be similar under similar relative creep loads. The relationships presented in this paper may be valuable to the practicing engineer dealing with structures supported on different types of fine‐grained frozen soils.
