| 摘 要： | 随着社会化进程的推进，顶管法在各类城市地下管线的施工中得到广泛应用。超浅层顶管施工。绝大多数是在已建道路下进行的，施工时，易发生地表沉降，且沉降量很大，易破坏路面。为此，超浅层顶管施工对周围环境的影响已引起人们足够的重视，其施工及控制技术是目前迫切需要掌握的。利用有限差分软件FLAC3D对顶管施工过程中地表沉降进行模拟，旨在了解超浅层顶管施工引起的力学效应。对超浅层顶管施工引起的地表沉降作出预测，为采取措施减小地表沉降提供依据。

| Abstract: | As the advancing of the socialization process,construction of the Pipe Jacking is widely used in the construction of various types of urban underground pipeline.Most of Ultra-shallow Pipe Jacking are carried out under the road has been built. It is early to generate large settlement which will cause damage to the road during the construction.People pay more attention to the impact on the surrounding environment when constructs.So it is urge to know the construction and control technology.The authors using the finite difference software-FLAC 3D to simulation the settlement of surface,in order to find out the mechanical effects of constructing,then predict the settlement and provide the basis for taking measures to reduce surface when constructing. |
