Abstract：Uniaxial compressive strength tests are conducted on the saturated frozen Lanzhou silt (loess) under various constant strain rates and various constant temperatures. From the test results，it is concluded that (a) compressive strength is very sensitive to temperature and increases exponentially as temperature decreases，(b) compressive strength is sensitive to strain rate and increases exponentially as strain rates increase within certain range，(c) compressive strength decreases exponentially as failure time increases，and (d) compressive strength of the saturated frozen silt with higher dry density is higher than that of frozen silt with lower dry density. The increment rate of compressive mainly depends upon strain rate.
