摘要
地震作用下尾矿库安全直接关系到矿区和下游人民生命、财产安全。以某尾矿库为例,运用MIDAS/GTS软件建立三维有限元模型,选取合适的模型参数,对黏弹性边界条件下的地震波予以合理输入,分别对无质量地基模型和黏弹性边界模型地震荷载作用下的应力及永久变形进行分析。研究结果可为类似工程提供相应参考。
The safety of tailings dam is directly related to the mining area and downstream people’s lives and property.Taking a tailing pond as an example,this paper uses MIDAS/GTS software to establish a three-dimensional finite element model,selects appropriate material parameters,and gives reasonable seismic wave input under viscoelastic boundary condition,the stress and permanent deformation of mass-free foundation model and viscoelastic boundary model under earthquake load are analyzed respectively.The research results can provide reference for similar projects.
