摘要
尾矿库灾害造成的损失是相当严重的。已经引起国内外学者的广泛关注。文章在详细调查分析国内外尾矿库由于失稳造成的各种灾害类型的基础上,总结了现有灾害的治理方法。将其归纳为改善坝体渗流条件、提高坝体密度及改善坝体受力条件3类措施。并对各种治理方法的适应性进行了探讨。根据加筋土结构补强原理,提出利用土工合成材料对尾矿库坝坡进行加固、绿化的设计理念。通过加筋尾矿砂的力学性质试验,表明尾矿砂是适宜用作加筋土填料的材料。
The loss caused by tailing disaster is considerable serious, which has widely brought scholar′s attention at home and abroad. This paper detailedly investigates and analyses the kinds of hazards caused by failure of tail reservoir at home. The control measures of the hazards and a new development design idea have been summarized. Three methods such as improving the seepage condition, enhancing the density and improving the bearing capacity of the slope have been defined. In the end, this paper discusses the degree of suitability for all kinds of method in hazard control. By using the theory of reinforcedsoil, the new think in design to reinforce and green the tail dam using geosynthetics is brought forward. According to mechanical trials of tail sand reinforced by geotextile, the tail sand as a feasible material can be used to build reinforcedsoil structure.
