| 摘 要： | 在不良地质隧道隧道施工过程中，突水涌水、塌方是最常见、危害最大的风险事故。怀通高速公路阳洞滩II号江隧道，洞口段埋深浅，且多为强风化砂质板岩，为国内外隧道施工难度之最。建立的模糊综合层次评估模型，评价料阳洞滩II号江隧道突水涌水、塌方风险，得出了洞口段的突水涌水、塌方风险等级。在此基础上，提出了风险控制技术措施，为隧道的安全施工提供了技术保障。

| Abstract: | Collapse occurs normally during tunnel construction in poor geology. Yangdontan II / tunnel exists in tiuaitong Expressway , entrance section is buried in shallow layer, and its surrounding rockmass is weathered sand-slate, a, it is the most difficult tunnel to be build in the world. With the fuzzy-hierarchy assessment model, Evaluation of collapse disater during a underground-water tunnel con- struction is made, which is the shallow and pre-pressure tunnel, and its disater degree is gained. The risk control measure are put forward, the result will provide guidance to construction. |
