基于模糊可拓方法的公路隧道施工风险评价的应用
|
摘要
为了公路隧道施工建设安全性,通过实例验证,从工程地质条件、山区隧道开挖断面、隧洞施工技术现状、洞口工程难易程度及其相应的12类指标对施工风险分析,结合专家给出模糊隶属度,采用模糊可拓方法将评价指标用特征数据矩阵来表征;再利用层次分析法求得的权重;最终求得各指标层的关联度;得到的评价结果与实际状态相符。表明该评估方法可应用于山区高速公路隧道施工风险评估领域,评估结果可为施工决策人员提供参考。
For the safety of highway tunnel construction,examples show that construction risks are analyzed from engineering geological conditions,excavation section of mountain tunnels,current construction technology of tunnels,difficulty of tunnel entrance engineering and its corresponding 12 categories of indicators.The fuzzy membership degree is given by experts,and the evaluation index is expressed by the characteristic data matrix using the fuzzy extension method.Then the weight obtained by the analytic hierarchy process.Finally,the correlation degree of each index level is obtained.The evaluation results are consistent with the actual state.It shows that the evaluation method can be applied to the risk assessment field of mountain expressway tunnel construction,and the evaluation results can provide reference for construction decision-makers.
