摘要
结合湖北某露天矿废石场的工程实例,采用现场坑探和室内大型直剪试验,获取废石的物理力学参数。在分析废石场边坡的破坏模式的基础上,采用4种极限平衡方法对3个典型剖面的边坡台阶安全平台宽度按6种情况进行优化计算,确定了废石场边坡最优结构参数,并提出了相关建议。
Taking an open-pit waste dump in Hubei province as the engineering project, the in-situ surveys and indoor direct shear tests were used to obtain the physical mechanics parameter of waste rock. Based on the analysis of failure mode for slope, security platform widths of slope steps for 3 typical sections were calculated and optimized under six situ- ations by 4 kinds of limit equilibrium method. Finally, the optimal structure parameter was determined, and relevant suggestions were put forward.
