水厂铁矿边坡加固设计及其稳定性分析

Slope reinforcement and stability analysis in Shuichang mine of China

对水厂铁矿北区边坡进行了工程地质调查研究,分析了滑坡现状和产生的原因,提 出了削坡锚固治理方案.采用FLAC有限差分法计算软件对加固前后的边坡稳定性进行了对 比分析.分析结果揭示了原边坡设计存在保守性和边坡不稳定性的矛盾,采取合理加固措施 是解决这一问题的关键,分析表明削坡锚固治理方案是有效合理的.

According to the investigation on geological condition in the north region of China's Shuichang iron mine, this paper analyzes basic features and reasons of the landslide, and suggests that the slope be stabilized by cutting slope and anchorage. A contrast analysis of slope stability is made between unreinforced and reinforced slopes by using FLAC Software. The results show that there is a contradiction between conservatism and unstability in the original slope design, and taking a reasonable reinforcement measure is the key to solve this problem. It is verified that the reinforcment is a very effective measure for this kind of unstable slope.
