摘要
修建于崇山峻岭之中的山岭隧道,由于其复杂的地质条件和施工扰动,造成坍塌、突泥、涌水等地质灾害频发。在此方面,为了达到减轻灾害的目的,普遍开展隧道施工前的安全风险评估和施工开挖后的稳定性评价工作,取得了显著的进展,但是鲜有施工过程中对此类灾害的潜在危险性和危害性的辨识和评估。本文采用模糊综合评价法对碑仔头隧道断层破碎带塌方风险性进行分析,详细阐述模糊综合评价法的具体应用,为隧道穿越断层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。
The mountain tunnel always in the moutains. The collapses, mud gushing and water inrush and other hazards frequently occur during tunnel construction by complex geological conditions and construction disturbance. In this regard, in order to achieve the purpose of disaster relief, the safety risk assessment before construction and stability evaluation after excavation are generally carried out. It makes significant progress, but there is little risk assessment and hazards identification for potential disaster in the construction process. This paper analysis a fault fracture zone of Beizitou tunnel by the fuzzy comprehensive evaluation method, elaborates the concrete application of fuzzy comprehensive evaluation method in detaiL It makes quantitative analysis of the risk for tunnel through the fault fracture zone , and it has important economic and safety significance significance to guide the construction.
