渗流与应力耦合环境下裂隙围岩隧道涌水量的预测研究

A Prediction Study of Water Gush Yield in Fractured Tunnels under Coupling between Seepage and Stress

涌水是隧道及地下工程施工中的重大地质灾害之一。对于裂隙围岩介质而言，由于其结构特性与所赋存环境的复杂性，使得这一问题的解决具有一定的难度。基于系统理论研究及工程实践的分析应用，本文在裂隙围岩介质渗透性能等效处理的基础上，提出了渗流与应力耦合环境下裂隙围岩隧道涌水量预测计算的确定性数学模型方法（包括理论解析法、经验解析法和水文地质数值模拟法）。

Water gush is one of major hazards in tunnels and other underground engineering. As the texture characteristic and exist environment of fractured rock is complex, it is difficult to solve this hazard in practice. Based on the equivalent treatment on seepage of fractured rock mass, the definite mathematical models (including theoretical analytic method, empirical analytic method and hydrologic numerical simulating method) are presented through theoretical and empirical study. Finally, the above mathematical models presented are applied in a tunnel engineering practice.
