摘　　要：对尾矿库487勘探线边坡饱和渗流与物化耦合作用下的稳定性进行分析,通过现场监测和试验得到边坡的力学参数。利用块体极限平衡法对四棱锥体从应力场、渗流场和物化耦合作用下边坡稳定性进行分析得到其安全稳定系数。利用ABAQUS软件模拟对比分析,得出坡体的滑移面、饱和度及在饱和渗流作用下的塑性区。通过边坡失稳评价准则得到边坡整体安全稳定系数与块体极限平衡法理论计算对比分析确定边坡可靠度。得出边坡在多场耦合作用下岩质边坡的稳定性降低,证实模拟的准确性。The slope stability of the tailings 487 exploration line under saturated seepage and materialization action is analyzed. The mechanical parameters of the slope are obtained by field monitoring and experiment. The slope stability of the four pyramid is analyzed from the stress field, the seepage field and the physicochemical coupling, and its safety and stability coefficient is obtained by means of the block limit equilibrium method. Using the ABAQUS software simulation and comparison analysis, the sliding surface, saturation and plastic zone under the action of saturated seepage are obtained. The slope safety reliability coefficient and the block limit equilibrium method are obtained by the slope instability evaluation criterion. It is concluded that the slope stability is reduced by the coupling of the multi - field, and the accuracy of the simulation is confirmed.
