摘要
为准确评价隧道突水对施工安全的影响,筛选地层岩性、地形地貌等8个水文地质指标作为隧道突水主要影响因素,建立突水风险评价体系,提出一种基于改进理想点法的风险预测方法。根据改进的模糊层次分析法和熵权理论分别确定指标的主客观权重,将主客观权重之和的最小值作为综合权重并动态修正。运用该方法对杨林隧道4个突水区域的风险等级进行预测,结果和现场实际情况一致,从而验证了该方法的适用性。
In order to correctly evaluate the influences of water inrush on the safety of tunnel construction,eight hydrogeological indicators such as formation lithology,topography and geomorphology were selected as the main influencing factors of tunnel water inrush so as to establish the corresponding risk evaluation system,and a risk prediction method based on improved ideal point method was proposed.The improved fuzzy analytic hierarchy process(AHP) and entropy weight theory were combined to determine the subjective and objective weights of indicators respectively,and the minimum weight sums between the subjective and objective weights were taken as the comprehensive weights and dynamically revised.Applying this method to predict the risk level of the four water inrush areas in Yanglin tunnel,the predicted results are consistent with the actual situation on site,indicating that the method is applicable.
