摘要
通过运用水动力学法、水均衡法、水径流法等方法对新七道梁隧道下行线部分典型区段的涌水量进行模拟计算,发现该段适宜选用解析法和水径流法,而水均衡法和水动力学法预测的涌水量偏大。而且运用数值模拟可以动态预测地下水渗流特征,是较好的地下水模拟预测方法。
Simulation calculation was made to the volume of water gushing in typical section of down line in Xinqidaoliang Tunnel by adopting methods of water dynamics, water equilibrium, water runoff and water analysis. It is found the methods of analysis and water runoff were suitable for calculation of volume of water gushing in this section, but the predicted volume of water gushing was overlarge by adopting methods of water equilibrium and water dynamics. Numerical simulation is a good way to simulate and predict the volume of underground water, which can predict the seepage characteristics of underground water.
