Abstract

It is important to master the creep properties of artificial frozen soil in engineering construction during the freezing in the shaft sinking .Given the shortage that the creep behaviors of artificial frozen soil were deemed as the materials between perfect solid and fluid, and that the components of integer order calculus constitutive relation were in great demand,the fractional order constitutive relation was used to calculate the creep character of the artificial frozen soil .Through the substitution of a multipled dashpot by a fractional order derivative dashpot, a fractional order derivative Kelvin’s creep model is developed. The series accelerated element are added to the fractional order element in Kelvin model, and the acceleratemodel is built. Using fractional order derivative Kelvin model to simulate the creep properties of artificial frozen soil, the model parameters was obtained by the global optimization of simulated annealing algorithm. The fractional order derivative creep model of artificial frozen soil can be reflected preferably in the 3 stages creep process.
