    ADVANCE ON THE METHODS FOR PREDICTING WATER INFLOW INTO TUNNELS

    • 摘要: 涌水灾害问题广泛存在于隧洞工程的建设之中,它直接关系到施工进度、洞室稳定性及人身安全。目前国内外学者研究出大量的隧洞涌水量预测计算方法,但不同计算方法具有不同的适用条件和优缺点,选取合理的计算方法对于计算结果的准确性至关重要。本文将当前广泛应用的隧洞涌水量预测计算方法分类总结为4种:经验公式法、解析公式法、数值计算法和物理模拟法。经验公式法多来源于大量工程案例的总结,着重于相似地质条件下隧洞涌水量计算;解析公式法则基于严密的理论推导过程,计算过程快速简洁;数值计算法适用于复杂水文地质条件下涌水问题的计算;物理模拟法借助于试验的手段,直观地显现出隧洞的涌水规律。本文对现有计算方法的理论原理、适用条件和优缺点进行了详细的总结,并展望了隧洞涌水问题的未来研究方向。

       

      Abstract: Groundwater inflow is one of the widespread disasters in underground tunneling, which directly affects the construction progress, the stability of the cave and resident safety. A large number of studies in predicting the groundwater inflow have proposed various methods associated with different application conditions. However, in order to accurately predict the groundwater inflow into tunnels, it is crucial to select a reasonable method for the specific condition. In this study, the previous methods are classified into four different types including empirical formula, analytical formula, numerical and physical simulation methods. The empirical formula method originates from the compilation of numerous engineering cases, focusing on similar geological conditions. The analytical formula method based on the strict theoretical derivations provides a fast and simple way for the assessment of groundwater inflow into tunnels. The numerical simulation method can analyze the complicated hydrogeological conditions. The physical simulation method intuitively characterizes the inflow laws by experiments. The theoretical principles, merits and drawbacks of these methods are summarized in detail. Furthermore, some potential research topics are prospected for further improvement.
