Analysis on the Influence of Slope Geometry on Stability Reliability in the Shitouping Scenic Area

Abstract:

There are a large number of natural slopes and artificial slopes in the upgrading project of the Shitouping scenic area in Jincheng Park of Lanzhou. Due to the variability of the physico-mechanical parameters of slope soils, the Monte Carlo random sampling method and limit equilibrium method were used to calculate and analyze the slope stability reliability indexes and the change rules according to different slope heights and gradients. The results show that the slope is stable and reliable in the area of the actual slope height and slope gradient range, which is suitable for the scenic spots construction. However, when the slope height and slope gradient reach the maximum or over-range of the actual range, the slope is in a basically stable or under-stable state, the reinforcement measures are suggested.
