摘要
分析了地铁隧道施工对邻近建筑物的影响因素及建筑物本身抵抗变形的因素,对地铁施工引起的环境建筑物的风险进行评价。应用可变模糊集理论,建立了地铁施工区间多个邻近建筑物安全风险排序模型及邻近建筑物安全风险评估模型,对隧道施工引起的邻近各建筑物的安全风险进行排序,并进一步评价建筑物安全风险等级。通过风险评价,可为地铁隧道施工前期风险源排查、采取合理的施工措施及保护措施提供依据,从而在保证邻近建筑物安全的基础上实现地铁隧道的施工。
During metro tunneling construction, one of the main targets is to ensure the safety of the adjacent build ings, therefore a safety risk evaluation of the buildings must be done before construction. By identifying factors that affect the adjacent buildings and their deformation re sistance ability, the safety risk grades are evaluated based on the variable fuzzy set theory, the order of risk degrees is also sequenced to further verify the accuracy of the evalua tion. By estimating the safety risk accurately, constructors will be able to take protective measures for the highrisky buildings adjacent to the metro tunnel.
