摘要
本文以某选矿厂尾矿坝工程勘察与稳定性分析为实例。系统地介绍了以探明尾矿坝工程地质、水文地质条件为目的的工程勘探手段和分析研究方法。在揭示了尾矿坝坝体材料空间分布状态及其力学特性的基础上，利用 Bishop 园弧滑动分析法和有限元法分析计算了尾矿坝浸润线的情况和尾矿坝的整体与局部稳定性，分析计算结果与现场勘测结果基本吻合。
Abstract
Taking the engineering exploration and stability analysisof the tailing dam of a concentration plant as example,this paper presentssystematicaily the means of engineering exploration and methodsused for the purpose of engineering geological and hydrogeologicalconditions of the dam.Having revealed the spatial distribution andphysic-mechanical properties of the dam body materials in the tailingsdam and having used Bishop Arc sliding analysis method and finiteelement method,the paper calculates the line of saturation as well as theintegral and local stability of tailings dam.The results of calculation andfield exploration are essentially in agreement with each other.
