摘　　要：以青岛胶州湾海底隧道青岛端接线工程开挖为研究对象,应用事故树分析法对可能引起地表建筑物受损的各种爆破振动因素进行定性分析,求出各影响因素的重要度,为后续监测和施工方案的调整提供理论依据.通过现场对爆破振动监测,确立振动传播衰减规律,并以此对地面建筑物进行安全性评价.研究成果对指导青岛后续地铁隧道工程开挖和保证地表建筑物安全有重要参考价值.Based on the excavation of Qingdao Jiaozhou Bay Submarine Tunnel Project,the factors about blasting vibration that may cause damage to the ground buildings were qualitatively analyzed by using the method of FTA in this article.It also provided a theoretical basis for the follow-up monitoring and adjustment of the construction program by obtaining the degree of importance of each factor.Through the field blasting vibration monitoring,the attenuation rules of vibration was established and thus the safety evaluation of the ground buildings conducted.The results of the researches provide important reference for Qingdao subway tunnel excavation and the safety of the ground buildings.
