Analysis of slope deformation under control of rock mass structure

Slope deformation and instability are prominent geological andgeomorphic feature of loess plateau and are the strong factor to cause disasters.

Down-slope overlapping,which was found in weak clastic rocks of middle triassic Badong group(T2b),is a slope deformation failure form proposed during the stability study of the reservoir bank of the Three Gorges Project.

Research purposes:The slope deformable body of Zhegu Mountain was a potentially large-sized sliding deformable body and it was in the creep deformation stage.

Study on effect of construction loads on longitudinal deformation of adjacent metro tunnels;

Through the mechanical analysis, the differential equation for the longitudinal deformation of cold forming steel is derived, and the formula for longitudinal rotation angle is obtained.

The longitudinal deformation of metro station in soft clay is usually controlled by thickening the flank wall and floors and increasing the longitudinal stiffness of the station,which will sometimes result in the increase of thermal stress and dry shrinkage stress of concrete and thus cause crack and leakage in the structure.
