%X It is of great significance  to master the creep law of rock-soil body under  frozen state for the safe shaft construction by using freezing method. We carry out uniaxial compressive strength tests for artificial freezing remolded clay at the temperature of -5℃,-10℃ , -15℃,respectively.Furthermore, we obtain the relationship between temperature and uniaxial compressive strength of artificial freezing remolded clay. According to uniaxial strength under  frozen state of remolded clay, we conduct creep test with  3 loading levels and obtain the  influence of temperature and loading level on creep. Furthermore, we introduce Abel dashpot into Nishihara model and establish fractional order derivative Nishihara model. Finally, by introducing ant colony algorithm into frozen remolded clay, we finish parameter identification for Nishihara creep model and fractional order derivative Nishihara model. Through analyzing simulated results in two models, we can find that fractional order derivative Nishihara model is more appropriate than creep Nishihara model in creep calculation for frozen remolded clay.
