摘要
为定量分析尾矿库水工结构设施受采动的影响和损害,针对水工构筑物的岩体地基的力学问题,即坝基岩体承载稳定性评价的重要力学计算点进行了探究。在对尾矿库水工结构设施进行论述后,对坝基岩体承载稳定性进行了公式推导计算及力学分析,分析了尾矿库坝基滑移而造成失稳的3种形式;并对尾矿坝体的深层滑动滑面倾向上游和滑面倾向下游的情况进行了受力分析和力学公式推论。此外,以尾矿库损害造成的各类影响结果为基础,建立了模糊综合评价模型,提出相应的建议和合理措施。结果表明,模糊综合模型对于尾矿库水工结构设施采动影响评价及损害防护探究是合理的,同时也为某尾矿库水工结构设施采动影响评价及损害的治理方案和策略制定提供了可靠的定量分析依据。
To analyze the main influences and damages caused by the mining of the tailings pond hydraulic structure,the important mechanical calculation points of the bearing stability evaluation of the dam foundation were analyzed.Based on the hydraulic structure of the tailings pond,the mechanical analysis of the bearing stability of the dam foundation rock mass were carried out,and the three forms of instability caused by the sliding of the tailings dam foundation were analyzed.To the deep sliding stability of the tailings pond dam body,the force analysis and the mechanical formula derivation were carried out under the conditions that the sliding surface tends to upstream and the sliding surface tends to downstream.In addition,based on the various impacts caused by damage to the tailings pond,a fuzzy comprehensive evaluation model was established,and the corresponding suggestions and reasonable measures were put forward.The results show that the fuzzy comprehensive model is reasonable for the impact assessment and damage protection of the tailings pond hydraulic structure,which provides a reliable quantitative analysis method for the damage assessment and treatment of the tailings pond hydraulic structure.
