| 摘 要： | 以温庄尾矿库为工程背景，通过室内堆坝模型试验，获得到了在坝体堆积过程中尾矿颗粒在库内沉积分布特征、浸润线的变化规律等基础资料。在此基础上，以多孔介质有效应力理论为依据，建立了多孔介质流-固耦合数学模型，利用有限元软件ABAQUS对该库尾矿坝的应力场与渗流场进行了分析，获得了坝体内的应力场及孔隙压力的分布规律，研究成果可为尾矿库的设计、施工和安全生产提供技术支撑。

| Abstract: | Taking the Wenzhuang tailings reservoir as project background,through indoor stacking model tests,the change law of saturation line and particle size distribution are obtained.Based on these results,a mathematical model of fluid-solid coupling in porous media is established;and by using the software of ABAQUS,a planar model of finite elements is established;and through finite element analysis,the stress field,deformation field as well as pore water pressure field in the dam are obtained.The results of model... |
