摘要
针对引水隧洞施工中塌方安全事故多发现象,研究隧洞塌方风险评价体系,为塌方灾害预测预警提供依据。首先通过整理隧洞塌方研究成果并结合实际工程,遴选出塌方的主要影响因素,构建隧洞塌方风险评价指标多层次模型;其次将熵权法、层次分析法相集成得到评价指标的权重;最后运用岭形分布函数、分级法评定指标的模糊矩阵,建立了隧洞塌方风险模糊综合评价模型。此模型应用于龙开口12号隧洞,其结果与施工实际情况相符。
In view of the frequent occurrence of collapse disasters in the construction of water conveyance tunnels,the riskevaluation system of tunnel collapse is studied to provide the basis for the prediction and early warning of collapse disasters.Firstly,the main influencing factors of collapse are selected by sorting out tunnel collapse research results,and a multi-levelmodel of tunnel collapse risk assessment index is constructed. Secondly,the entropy weight method and the analytic hierarchyprocess are integrated to get the weight of evaluation index. Finally,the fuzzy matrix of index is evaluated by the ridgedistribution function and the grading method,and the fuzzy comprehensive evaluation model of tunnel collapse risk isestablished. This model is applied to the evaluation of No. 12 tunnel in Longkaikou project,and the results are consistent withactual construction conditions.
