某隧道施工塌方风险模糊综合评价
摘要:公路隧道施工塌方是隧道建设中最常见的风险之一。近年来,隧道工程施工塌方事故呈增长趋势,给隧道施工安全和质量带来了巨大的影响,因此对隧道作风险评价尤其重要。通过收集公路隧道施工塌方案例历史资料,找出七个影响施工塌方的最主要的风险因素为围岩等级、地下水情况、埋深、跨度、偏压、爆破扰动、施工管理水平。分析比较各个因素相对公路隧道塌方的影响程度,再基于模糊综合评价法和频数分析法确定风险因素的评价矩阵和相应权重,得到模糊综合评价模型,该模型根据隧道具体情况以及模糊数学的概念得出隧道风险评价结果,在实例中得到验证,具有较高的客观性和实用性。
Abstract:The highway tunnel collapse in tunnel construction is the most common disaster accidents, so the tunnel for the risk assessment is particularly important, through the collection of highway tunnel landslide case history information; and comparing various factors relative to the important degree of highway tunnel collapse, find out the seven effects in the main risk factor for the class of surrounding rock, groundwater conditions, buried deep, large span, bias, blasting disturbance, construction management level, and then based on the fuzzy comprehensive evaluation method and frequency analysis method to determine the risk factor evaluation matrix and the corresponding weight, get the fuzzy comprehensive evaluation model, the model according to the specific situation of tunnel and the concept of fuzzy mathematics the tunnel risk assessment results, in the example verified, with the higher the objectivity and practicability.
