| Abstract: | Based on the miaxial constant strain-rate compression tests on frozen soils, it is proposed that the stress-strain behaviour of frozen soil can be classified into 9 types and their corresponding stress-strain equations are also given. The test results show that for a certain type of soil its stress-strain behaviour mainly depends upon strain rate and temperature. According to the ranges of strain rate and temperature for the 9 types of stress-strain behaviour, the constitutive relation maps of various kinds of frozen soils in uniaxial compression were firstly presented. And, they are important for the design of frozen soil foundation and structures. |
