尾矿坝稳定性评价研究

摘 要 随着国内矿山开采的规模不断扩大，大量尾矿库的建设致使尾矿坝的稳定性评价越来越重要。目前尾矿库的按照筑坝方式可分为：上游式堆坝方法、中线式堆坝方法、下游式堆坝方法。本文对比不同筑坝方式的优缺点。本文结合工程实际，通过有限元软件 Geostudio，通过分析安全系数，滑移面安全图，得出筑坝方式对于尾矿坝的稳定性的影响规律。关键词：尾矿坝；筑坝方式；稳定性；Geostudio。IAbstractWith the continuous expansion of domestic mining, the construction of a large number of tailings reservoirs has made the stability evaluation of tailings dams more and more important. At present, the tailings pond can be divided into: upstream stacking method, midline type dam method, and downstream dam method according to dam construction methods. This paper compares the advantages and disadvantages of different dam construction methods. Based on the engineering practice, this paper analyzes the influence of dam construction method on the stability of tailings dam by analyzing the safety factor, stress cloud map and displacement cloud map through the finite element software Geostudio.Key words: tailings dam; dam construction method; stability; GeostudioII目录摘 要.............................ERROR: REFERENCE SOURCE NOT FOUNDABSTRACT...........................................................1第一章 绪论................................................................................................................11.1 研究背景及意义..............................................................................................11.2 国内研究现状.................................................21.3 主要研究内容.................................................2第二章尾矿库资料及筑坝工艺分析................................42.1 概述.........................................................42.2 尾矿坝的特色.................................................52. 3 场地危险性分析................
