基于系统理论研究及工程实践的分析应用,提出了渗流应力温度耦合环境下大埋深裂隙围岩隧道涌水量预测计算的确定性数学模型方法( 水文地质数值模拟法) ,并通过一隧道工程实例进行了计算验证“,”Water gush is one of the major hazards in tunnels and other underground engineering. Because the texture characteristics and the existing environment of fractured rock are complex, it is difficult to solve the problem of water gush in practice. In this paper, based on an equivalent treatment on seepage of fractured rock mass and on theoretical and empirical study, a definite mathematical model, hydrology numerical simulation method, is proposed for predicting the water gush yield of the deep buried fractured surrounding rock tunnel. Meanwhile, the proposed mathematical model is verified through an example of tunnel engineering.
