| 中文摘要: |
| 文章通过搜集已有工程地质资料,并采用钻探、标准贯入试验、取土试样及室内试验等相结合的勘察方法,获取尾矿库各岩土层物理力学性质指标,根据对尾矿库在现状库内水位正常运行、洪水运行和特殊运行3种工况下的坝体抗滑稳定性计算分析,采用瑞典圆弧法和简化毕肖普法,进行坝体渗流、抗滑、液化稳定性分析,经过计算分析,安全系数满足规程要求。 |
| 英文摘要: |
| Through collecting the existing engineering geology data, the study obtained physical and mechanical property indexes of every rock soil layer in the tailing by the method of combining drilling, standard penetration test, soil samples and laboratory tests. According to the analysis of anti sliding stability of the tailings in the present situation of library water level in the normal operation, flood operation and special operation three cases under the dam, the paper analyzed the dam seepage, anti sliding and liquefaction stability, using swedish circle method and simplified bishop method.Through calculation and analysis, the safety factors meet the requirement of the regulation. |
