【摘要】为预测云南兰坪铅锌矿温庄尾矿坝在未来运行中的稳定性,进行了室内土工实验,分析了铅锌矿尾矿的物理力学性能,同时通过ABAQUS有限元软件,建立了温庄尾矿坝的二维流固耦合模型,获得了该尾矿坝在正常和洪水两种工况下的应力场,位移场,渗流场的结果。更多还原

【Abstract】 In order to forecast stability of Wenzhuang Tailings Dam of Lanping Lead-Zinc Mine in Yunnan in future,geotechnical tests were conducted in a laboratory.The physical mechanics properties of lead-zinc tailings were analyzed.A two dimensional coupling model of fluid and solid of Wenzhuang Tailings Dam was established by ABAQUS finite element software,and the results of stress field,displacement field and seepage field of this tailings dam normal and flood were achieved.更多还原
