In order to settle the basement of deformation simulation and numerical analysis of Xietan landslide in the Three Gorges
the drained triaxial compression creep tests with the constant stress on landslide zone soils have been carried out. Based on those tests and supposed that c
are independent on time and
G
D
n
depend on time
a Duncan-Chang E-μ model which depends on time is presented. Through the simulation of test data
the behaviors of k
and time are given and 12 parameters in that model is given also. In the end
through contrast of computed curves by model and test data
that model is proved to be suit to such landslide zone soils in Xietan landslide.
