| 摘 要： | 重庆市同茂隧道地处老城区,开挖跨度大、埋深浅、上覆建筑物密集、类型多且年代已久,为隧道设计和施工带来了一定的难度。结合同茂隧道工程实际,以框架结构建筑物为研究对象,建立三维有限元模型,通过隧道施工过程对建筑物影响的有限元分析,主要对桩基变形及框架结构的弯矩、轴力和变形进行了研究,揭示桩基变形及框架结构的弯矩、轴力和变形随施工过程的变化规律。本研究可为类似工程隧道施工对上覆框架结构建筑物的影响研究提供借鉴和指导。

| Abstract: | The Tongmao Tunnel located at old city in Chongqing has a large span and is shallow buried.The Overlying structures of this tunnel are intensive,varietal and old.Combined with Tongmao tunnel project,the overlying frame structure building was taken as research object,a three-dimensional finite element model was constructed,and the influence of the tunnel construction process on the building was analyzed.It focuses on piles deformation and the bending,axial force and deformation of the frame.Change features of piles deformation and the bending,axial force and deformation of the frame can be reviled.It can provide guidance to the influence of similar tunnel constructions on overlying frame structure buildings. |

| Keywords: | tunnel construction numerical simulation frame structure piles deformation the internal force of structure |
