摘要： 山岭隧道修建于崇山峻岭之中，由于其复杂的地形地貌和地质条件，施工过程中坍塌、突泥、涌水等地质灾害频发。为了防灾减灾，均需要进行施工过程中的监控量测和超前地质预报工作，但是施工过程中针对具体灾害的潜在危险性和危害性的风险辨识和评估工作仍有重大工程价值。采用模糊综合评价法对增坂隧道构造破碎带的塌方风险进行分析，详细阐述该方法的应用，为隧道穿越构造破碎带时施工风险性做出定量分析，对指导施工具有重要经济意义和安全意义。

Abstract: Tunnel constructions in the mountain terrain frequently have geohazards, such as, collapse, sudden rush of mud and water, due to their complicated geological and topographical conditions. To minimize these geohazards, it is necessary to monitor the construction to predict the potential risks. Evaluating the specific hazard and its potential influence on the construction still has engineering importance. The collapse potential of Zengban Tunnel in the broken rock mass is evaluated by the comprehensive fuzzy approach method. This paper illustrates the details of the application of this method and the quantitative approach of the potential risk.
