GeoStudio软件Slop-W模块在堆浸场边坡稳定性分析中的应用

堆浸场边坡稳定性对于矿山堆浸场的经济性和安全环保性方面具有重要意义。基于极限平衡条分法原理开发的GeoStudio软件,其中的Slop-W模块作为一种岩土结构稳定性分析通用软件,能通过建立有限元模型,施加荷载和边界条件,有效模拟土条受力以及土条间作用力,建立力平衡和力矩平衡方程,求解堆浸场最危险滑弧以及最小安全系数,从而全面掌握堆浸场边坡抗滑稳定性。本文通过该软件在工程实例中的应用,为今后堆浸场的稳定性安全设计和评价提供了一定的参考依据。

Application of GeoStudio Software Slop-W Module in the Slope Stability Analysis for Heap Leaching Field

The slope stability of heap leaching field is of great importance to the economic , safety and environmental protection of the heap leaching field. The software GeoStudio was developed on the base of limit equilibrium principle.The Slop-W module in the GeoStudio was widely used in the rock and soil structure stability analysis.The Slop-W module can establish the force equilibrium and also the moment equilibrium equations for the heap leaching,through establishing the finite element model, applying loads and boundary conditions, and simulating the effective soil stress and forces between slices.The position of the most critical slip circle and the minimum safety factor can be obtained, so as to fully grasp the safety condition against sliding of the heap leaching field. Through the application of this software in an engineering practice, this paper provides a reference for the stability safety analysis and evaluation of the heap leaching field in the future.
