国道K2 330工点发生大型滑坡 ,重新削坡后仍然存在滑坡的危险 ,需对其稳定性进行评价 ,为边坡加固处治方案的制定提供依据。对该边坡引用赤平极射投影方法和余推力法两种稳定性分析方法进行定性和定量评价。 Large landslide occurred at State Highway K2 330, and there is still danger of landslide after the new slope cutting. The stability of the landslide should be evaluated to provide the basis for the formulation of the slope reinforcement treatment plan. The method of qualitative analysis and quantitative evaluation of two kinds of stability analysis methods of the slope with reference to the stereographic projection method and the residual thrust method are introduced.
