Abstract: Uniaxial unconfined compressive strength tests are conducted on Shanghai frozen clay which have three different water contents. Through the analysis of experimental results, the compressive strength of frozen clay is affected by temperature, loading rate, water content and dry density. Test results show that the lower the temperature and the greater the loading rate, the higher the compressive strength of frozen clay. The parameters of exponential function model concerning compressive strength and temperature as well as the parameters of power function model concerning compressive strength and loading rate are deduced. It is also established the equation of compressive strength based on the variables of temperature, loading rate and water content (or dry density). By orthogonal analysis, the influences of each factor on compressive strength of frozen clay are in the following descending order: temperature, loading rate and water content.

Key words: frozen clay, uniaxial compressive strength, loading rate
