摘要
针对渗透破坏影响尾矿坝安全问题,以尾矿坝工程为例,采用有限元方法,构建了不同排渗墙布置方案的有限元模型,模拟了排渗墙及其排水管等结构的渗流特点,分析了其降低坝体浸润面的能力,最终确定了排渗墙的尺寸和位置。
Taking tailings dam project for an example,different seepage wall layouts of finite element model are built to discuss the safety issues of the tailings dam causing by seepage damage.And the seepage characteristics of the seepage wall and drainage pipeline are simulated by using finite element method.Then the ability of seepage wall in reducing phreatic surface of dam body is analyzed.Finally,the size and location of seepage wall is determined.
