Meantime, the creep stability criteria of rock sample, analytic expressions of the creep deformation, the creep speed and the creep acceleration are given.
同时，得出岩石试件蠕变稳定性的判别准则和蠕变变形、蠕变速率和蠕变加速度的解析表达式。

This model can well describe the variation ofcreep in the period of attenuation, steady period and period of acceleration. The validity of the model is verified by experimental data.
The shear and rheologic tests related to sliding soil within landslide zones are conducted and long-term strength as well as critical strength ofaccelerationcreep are obtained accordingly.
