Slope stability analysis and appraise of Dong-Gang combined pumphouse

Slope is a natural geography widely exists in the world. Reforms of the nature also lead to vast artificial slopes. Under the effect of inner force and various external loads, the stress-strain relationship of the slope is continuously changing and leads to kinds of destabilizing accidents. Accidents of slumping spread across the world, bringing in great loss to many countries and districts. Therefore, it is an important content of rock and soil engineering to study the stability of slopes. In this paper, combined with the engineering example, We introduce the method for slope stability analysis, and analyze the stability of the slope according to excavation grade ratio of 1:1.5. Considering the factor of water and earthquake, it calculates the stability factor and broken mode under four kinds of work conditions, and puts forward some solutions.
