隧道涌水量模糊综合评价法研究

在不同隧道工程中影响涌水量的主要因素不同，且各因素之间相互干扰，导致当前隧址区涌水量预测方法针对不同隧道的广适性较差。对此，总结了目前主流的涌水量预测方法，对其优缺点和适应性进行了比较，并将涌水量影响因素分为5个一级权重指标和10个二级权重指标，提出了基于模糊综合评价法的隧址区涌水量预测方法，最终得到涌水量等级。根据与实际工程的实测涌水量对比结果表明，该方法可以对隧址区涌水量范围有较为准确的预估。

Study on Fuzzy Comprehensive Assessment Method in Prediction of Water Inflow into Tunnels

The main factors that affect the amount of water inflow are different in different tunnel projects and these factors often influence each other. As a result, it is not easy to find out a common method to predict the amount of water inflow in tunnel engineering. This paper summarizes the current forecasting methods of water inflow and compares its advantages and disadvantages. What’s more, these factors are divided into five first-level weight indexes and ten secondary weight indexes. The method to predict water inflow in tunnel area based on fuzzy comprehensive evaluation method is proposed and the level of water inflow is obtained. According to the comparison with the actual measured statistics, this method can provide a more accurate estimate of the range of water inflow in the tunnel area and it is instructive for the specific engineering evaluation and selection of the existing water demand forecasting formula.
