ABSTRACT
In the case of the Lijiaxia hydropower station, creep sliding mechanism of the reservoir landslide and creepage property of the soil in the sliding zone is theoretically studied from the viewpoint of dynamics and on the basis of systematic analyses of the monitored landslide deformation data. A representative sliding block is selected to execute the slide acceleration test by simulating the operational conditions of the reservoir and the creep sliding mechanism is proved again. Creep sliding mechanism of the reservoir landslide and creepage property of the sliding-zone soil is theoretically studied from the viewpoint of dynamics. The tests indicate that when the shear stress acting on the sliding-zone soil lies between the long-term strength and critical strength, shear creepage of the sliding-zone soil is actually deceleration creepage. The landslide dynamic analysis should incorporate mechanics theory of creep sliding mass.
