摘要
数值模拟分析技术已广泛地应用于岩土工程领域。本文所探讨的正是如何应用此技术来解决边坡稳定性问题,为以后的边坡稳定性分析工作提供了经验借鉴。
     本文针对云南锡业公司老厂锡矿网选边坡工程地质条件,采用极限平衡法、三维有限元法和离散元法对网选边坡稳定性进行了计算机模拟研究,这三种方法各有优缺点,联合应用可互为补充,最后得出结果与实际情况比较吻合。同时利用极限平衡法对网选边坡稳定性的敏感度进行了计算分析,通过对计算结果的分析,得出了影响网选边坡稳定性的主要因素,从而为边坡处置提供了依据。本文系统地、全面地进行了边坡稳定性分析,提出加固处置措施,为矿山提供了可靠的理论依据。
Numerical analog analysis technique has been widely applied to geo-technical engineering. This paper has exactly discussed how to solve the problem of slope stability and being an experience for the later analysis of slope stability .
    In consideration of the geological conditions of WangXuan slope of Lao Chang Tin Mine in Yun Xi Company, Based on limit balance method , three dimensional finite element method(3D) and discrete element method, computer analogue and calculations analysis are carried out to WangXuan slope. The three methods all have merits and defects, they each can be supplementary to the other through associate application, the outcomes and the practical conditions matched well. At the same time by utilizing the limit balance we calculate and analyze the sensibility of Wang Xuan slope. Through the analysis of calculating results, we get the main factors of affecting the slope stability of Wang Xuan slope, and then the results provide the evidence for slope disposal. In this way, the stability analysis of slope is made systematically and completely and provid the way of reinforcing disposal, which has provided reliable basis of theory proof for mine.
