Stability analysis of limestone high-steep slope in an open-pit mine in Sichuan Province
In order to study the stability of high and steep open-pit slope,taking the limestone slope of an open-pit mine in Sichuan Province as the engineering background,a typical profile analysis was selected,and the stability analysis and evaluation of rock slope were carried out by using the stereographic projection analysis method.The rigid body limit equilibrium method of strength theory,two-dimensional finite element numerical simulation and three-dimensional numerical simulation were used to verify and compare each other.The research results show that:The overall slope safety factor of a typical section under three working conditions meets the requirements of the specification,and the overall stability of the slope is good.The conclusions obtained provide theoretical basis and data support for the later construction design,and provide reference for the slope stability analysis of similar projects.
