摘　　要：基于扰动情况下岩体应力场与渗流场相互作用机理,确定了应力场环境下岩体渗流参数的计算公式以及耦合模型中渗透体积力的加载方程,采用有限元分析软件ANSYS,运用物理环境耦合方法,介绍了水库下伏扰动岩体渗流场模拟分析的方法及流程,并对某库区下伏岩体渗流场进行了模拟分析,通过对该库区下伏采空区渗流场进行分析,对库区及采空区提出了处理建议.The hydraulic character of disturbed rockmass has more and more attached importance to rock engineering in recent years, and subsequently how to analyze the seepage field has come to be a desirable problem quantitatively. Based on the interaction of stress field and seepage field, the seepage parameters have been confirmed under the stress circumstance; then the loading equation of penetrating force of the coupling model has been certain. Whereafter, the simulating method and technical process has been particularly presented with FEM software ANSYS; and the water head isopleths map of profile seepage field and hydraulic pressure isopleth map of the mined-out area under the reservoir have been confirmed. Finally, the disposal proposal of the mined-out area and the reservoir is suggested based on the simulating analysis.
