| 摘 要： | 针对某水下过江隧道,采用浅埋暗挖法施工,隧道顶板最小厚度只有14m,且多为强风化泥质砂岩,为国内外隧道施工难度之最.采用的模糊综合层次评估模型对某水下隧道河底超浅埋段进行突水涌水、塌方风险评估,得出此段的突水涌水、塌方风险等级,为隧道的安全施工提供了技术指导.

| Abstract: | A underground-water tunnel is excavated by shallow excaved method,the thinnest of tunnel roof is only 14 m,and the most parts of the surrounding rock are strongly weathered mud-sand stone,which is the most hardest tunnel to build.Based on the fuzzy-hierarchy assessment model,of collapse disater for a underground-water tunnel was made,and its disater degree was obtained.The assessment results can provide a guidance to construction. |
