摘　　要：为探究同步施工时高层建筑对新建隧道结构的影响,通过MIDAS-GTS模拟高层建筑修建过程,并对临近隧道结构的位移及应力情况进行数值分析,采用地层-结构计算模型,分析在临近隧道区域修建高层建筑物时对隧道结构的影响,进而判断隧道承载能力及安全性能。数值计算结果表明:同步施工时,高层建筑物修建对临近隧道结构所产生的附加荷载及位移影响较小,均未超过隧道受力及沉降控制值,隧道结构处于安全状态。In order to explore the influence of high-rise buildings on the new tunnel structure during synchronous construction,MIDAS-GTS was used to simulate the construction process of high-rise buildings,and the displacement and stress of the adjacent tunnel structure were numerically analyzed.The stratification-structure calculation model was used to analyze the influence of high-rise buildings on the tunnel structure in the adjacent tunnel area.Then the bearing capacity and safety performance of the tunnel are judged.The numerical results show that the additional load and displacement caused by the construction of high-rise buildings have little influence on the adjacent tunnel structure during the synchronous construction,which do not exceed the control value of the tunnel force and settlement,and the tunnel structure is in a safe state.
