摘　　要：通过分析影响隧道贯通的误差来源,应用误差传播定律对贯通误差进行预计,给出了贯通误差预计的计算公式。结合青岛地铁1号线跨海段隧道狭长、地质条件复杂、光线暗等实际情况,对贯通误差进行估计,给出了具体测量方案,贯通结果表明:该方案有效保证了过海隧道的精准贯通;通过贯通后实际测量,水平贯通误差5.2 mm、高程贯通误差9.0 mm,验证了贯通误差预计方案的可行性,对相关工程提供了有益借鉴。In this paper,by analyzing the error sources that affect the tunnel through,the error propagation law is applied to predict the breakthrough error,and the calculation formula of the penetration error prediction is given.Combined with the actual situation of Qingdao Metro Line 1 cross sea section tunnel,such as narrow and long tunnel,complex geological conditions,dark light and other actual conditions,the breakthrough error is estimated,and the specific measurement scheme is given.The breakthrough results show that the scheme effectively ensures the accurate breakthrough of the cross sea tunnel;through the actual measurement after the breakthrough,the horizontal penetration error is 5.2mm,and the elevation penetration error is 9.0mm,which verifies the penetration error prediction scheme.It provides a useful reference for related projects.
