| 摘 要： | 首先研究裂隙岩体中应力场改变对地下水渗流场的影响作用机理,推导出渗透系数k和给水度μ受应力影响的表达式,进而分析渗流场的变化,地下水的作用引起应力场环境变迁,导致裂隙岩体的渗透变形,在此基础上建立了裂隙岩体中应力场与渗流场耦合作用研究工作程式和具"点荷载"特征的等效连续介质耦合数学模型,并应用于一隧道工程实例进行了计算.

| Abstract: | The thesis studies the mechanism about seepage field changing due to the stress field changing in fractured rock mass; educes the formulae of k and μ that effected by stress; then analyzes the seepage field changing and the stress field changing aroused by effect of groundwater. In this situation, study form of coupling action and coupling mathematical model on equivalent continuum media are presented through theoretical and empirical analysis. Finally, the above mathematical model presented is applied in a tunnel engineering practice. |
