试析基桩施工对邻近盾构地铁隧道变形的影响

现代城市的发展中,大量建筑都采用基桩结构承力,而当该工程项目和临近的盾构地铁隧道间距较小时,则容易对该结构的稳定性造成不利影响,最主要的影响为隧道结构变形。本文研究了桩基施工对临近盾构地铁隧道变形量方面造成的影响,之后探讨了在基桩结构施工过程中,引起的隧道变形量控制方法,从而严格保障盾构地铁隧道的安全程度。

In the development of modern cities,a large number of buildings adopt the bearing capacity of foundation pile structure.When the distance between the project and the adjacent shield subway tunnel is small,it is easy to cause adverse impact on the stability of the structure,and the most important impact is the deformation of the tunnel structure.This paper studies the influence of pile foundation construction on the deformation of adjacent shield subway tunnel,and then discusses the control method of tunnel deformation caused by pile foundation construction,so as to strictly guarantee the safety of shield subway tunnel.
