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 test and numerical simulation can provide instructor for the design

construction and safe production of tailings reservoirs.
