Analysis on Stability of Water-Saturation Slopes Based on the Cusp Catastrophic Model
摘要
Abstract
This work analyzed the stability of slopes in open mine pits under various saturation conditions. Based on the theory of cusp catastrophe, considering the deterioration of the rock mass on the landslide by variations of water level in the pit,a cusp catastrophic model under water saturation was established. Analysis shows that saturations can weaken the rock body on the slope,which can be described by a negative exponential law. Then according to this law,a nonlinear saturated water weakening function and a constitute equation were constructed. The discriminant of the cusp catastrophe model in-dicates that with increasing damage to the rock, the discrimination value approaches to 0,implying the slope turns from stability into instability. The re-search results can provide useful lines of thought for the analysis of the stability of bank slopes with weak structure or affected by the water level of reser-voirs.关键词
