Abstract

Taken the natural loess slopes in the Linfen area as the engineering example, analyze the relationship between the slope size parameters (height of slope, angle of slope), material parameters(soil cohesion, friction angle) and the stability safety coefficient of slope with different calculation method. The results show that: Different limit equilibrium method has less influence on the height of slope, cohesion and friction angle than angle of slope. The safety coefficient of loess slope have a good correlation to the high, cohesion and friction angle of the slope. The height of slope is negatively related to the safety coefficient, but the cohesion and friction angle are positively related to safety coefficient. The influence of cohesion and friction angle is greater than the height on the safety coefficient of slope. Therefore, we should pay special attention to parameters of cohesion and friction angle values in the stability calculation of loess slope.
