岩溶隧道风险等级模糊综合评价

为了获得已探明有溶洞存在时的隧道发生涌水突泥的风险等级,针对叙大铁路有溶洞存在的中坝隧道,选取了针对性的指标体系:溶洞规模,建立了相应的模糊综合评价模型,并采用层次分析法计算各项风险指标的权重,从而得出在有溶洞存在时这一特定条件下,隧道发生涌水突泥风险级别。

Fuzzy Comprehensive Evaluation of Karst Tunnel Risk Grade

In order to get the risk grades of water bursting and mud surging of tunnels at the presence of karst cave, this paper selects karst cave scale of the targeted index system according to the Zhongba Tunnel at the presence of karst cave on Xuda Railway. It has established the corresponding fuzzy comprehensive evaluation model and adopted the analytic hierarchy process for calculating the weight of various risk index to identify the risk grade of water bursting and mud surging of tunnels at the presence of karst carve.
