Abstract
Take the example of plane-shoving slide collapse in Tongjiang, by the analysis on the formation conditions and incentive mechanism, the control measures are obtained.For the shape, a group of paralleled tension cracks develop above the steep rock with width of 1m, both sides is enclosed.In heavy rainfall, the surface water flow into the cracks, in addi-tion to the hydrostatic pressure and hydrodynamic pressure, the splitter action of instantaneous high head in cracks promotes the development of cracks.At the same time, the sand stone layer of the upper part will push outward along the weak inter-layer; while the free surface is produced by extruding shift, collapsing will occur.This model is plane-shoving shift, collap-sing, shift again and collapsing again.In order to eliminate the hidden troubles of this type of landslide disasters, in the premise of collapse control, reducing effects of water on the slope must also be considered, as well as the engineering meas-ures to prevent cracks.关键词
