摘　　要：地质条件复杂的青岛地铁一期工程隧道在下穿质量状况各异、结构基础形式多样的建筑群时,建筑物的安全成为决定隧道施工进度和环境安全的关键。在分析建筑物安全风险作用因素的基础上,依据地铁隧道的相关资料和下穿的20栋建筑物现场检测鉴定结果,引入模糊数学综合评判方法,总结了两大类9种主要作用因素;分别建立隶属函数并选取相应权重,对不同程度的建筑物风险予以模糊综合评价,划分了其风险等级,以供工程施工作参考。The Ist phase of Qingdao subway project fea- tures complex geological conditions, it crosses under build- ings of different quality status, structural forms and bases, thus the building protection is very crucial for environment safety and tunnel engineering. Based on the analysis of risk contributing factors on buildings＇ safety, and according to the related materials of subway tunnel and the survey result of 20 on-site buildings, fuzzy comprehensive evaluation method is introduced in risk assessment and rating, 2categories of 9 key affecting factors are summarized, the membership function and the correspounding weight of these factors are determined respectively, which are used for the fussy comprehensive evaluation of the anticipated buildings safety, in order to classify the risk levels for tunnel engineering.
