摘要
涌突水灾害是隧道工程中常见的灾害,准确预测涌水量的大小对于保证隧道施工、降低隧道施工风险具有重要意义。通过实例研究,分别利用理论计算法和层次分析-模糊综合评判方法预测隧道涌水量。与实际发生的涌水量对比,理论计算法操作简单,但预测不够准确。随机数学方法考虑影响隧道涌突水多方面因素,并用权重来控制各因素对隧道涌突水的影响程度,预测结果和实际发生的涌突水能较好地吻合。由此证明了层次分析-模糊综合评判方法的适用性。
Water-gushing is the most general disaster in tunnel engineering.To ensure tunnel construction safety and reduce the risks in tunnel construction,it is meaningful to forecast water gushing accurately.Through cases studies,theoretical calculation method and AHP-FUZZY method were used to predict tunnel water-gushing respectively.Compared the results with the actual gushing yields,theoretical calculation method was simple,but not very accurate.AHP-FUZZY method considered many factors which affect tunnel water-gushing and used the weighted value to control the influence degree of each factor,its forecast results can fit the actual gushing water better.This proved AHP-FUZZY method to be more applicable.
