不同施工方式对既有地铁隧道的影响分析

Analysis on Influence of Different Construction Methods on Existing Subway Tunnel

摘要:

以深圳机场九道的道路及管线施工上跨地铁隧道为背景，分别采用放坡开挖和顶管施工方式，通过MIDAS软件建立了2种施工方式的二维和三维模型，分别统计了各种情况下地铁隧道的横向、纵向位移，对不同施工方式进行评估分析，为后续施工提供了一定的指导意义。

Abstract:

Taking the construction of the road and pipeline of Shenzhen Airport 9 th Road overpassing the subway tunnel as the background, the slope excavation and pipe-jacking construction methods are adopted respectively. The 2D and 3D models of two construction methods are established through Midas software to calculate the transverse and longitudinal displacements of the subway tunnel under various conditions, and evaluate and analyze the different construction methods, which provides some guidance for the subsequent construction.
