Stability Analysis Of Talus Slpoe

With the improvement of living standard and the change of life idea,People began to choose the weekend, holiday travel, leisure,The rapid development of China’s tourism industry,And a lot of scenic spots located in the mountains.For the increasingly prosperous mountain tourism,Inappropriate development and utilization of scenic spots,Geological disasters occurred in the scenic spot,The stability of rock slope is more typical,So it is very necessary to study the stability of rock slope.This paper based on the Qinglong xia Shuijingshanzhuang disaster prevention project, first analyzes the stability of talus slope cliff and local rock the trailing edge, then analysis of stability of talus slope by limit equilibrium method, then use the numerical simulation method to evaluate the stability of the slope, finally, according to thecomprehensive evaluation results, the reasonable measures for the prevention and control of rock slope are put forward, the main research results are as follows:1,Through analysis, The overall stability of the trailing edge of the rock slope is better, The local stability of rock under the condition of natural,under the rainstorm, earthquake condition may have loca; rock caving.2, Using the limit equilibrium method(transfer coefficient method, Sarma method), The stability of talus slope is analyzed:(1) natural conditions(trailing edge without collapse), The slope is in stable state and steady state; Natural conditions(trailing edge collapse), The slope is in unstable state.(2) heavy rain conditions(trailing edge without collapse), The slope is in unstable state; Heavy rain conditions(trailing edge collapse), The slope is in unstable state;(3) earthquake conditions(trailing edge without collapse), Slope is in unstable condition; Seismic condition(trailing edge collapse), Slope is in unstable condition.3, Through the FLAC3 D on the talus slope at the trailing edge of the landslide occurred, there is a collapse of the natural, heavy rain, earthquake conditions to simulate, The distribution of displacement, shear stress and plastic zone under different working conditions are obtained, The safety factor calculated by the strength reduction method, When the slope of the slope is not collapse, the plastic penetrating area occurs under the condition of heavy rain and earthquake, The slope instability. The trailing edge of the slope collapses when there is a collapse, Natural, heavy rain, earthquakes have occurred in the three conditions of plastic through the area. So, the collapse effect of talusslope trailing edge of rock, The stability of the slope has been changed.4, According to the situation, Combined with comprehensive evaluation, The reasonable control measures are put forward for thetalus slope, "Building drainage ditch,Rock removal, rockconditions cut unloading, slope bottom wall, built along the cliff set up warning signs" for comprehensive treatmengt.
