顶管施工对周围土体扰动的影响研究

在城市地下隧道建设中,顶管法是一种较为隐蔽的地下暗挖施工方式,具有减少道路拥堵、环境污染等作用,在现如今实际工程中已经广泛应用.其在施工过程中会对周围土体产生较为明显的影响,具体表现为地表沉降,隧道周围土体会发生不同程度的挤压变形.文中结合苏州城区某顶管施工工程,顶管下穿既有交通轨道,主要对2 号线周围土体进行位移监测,分析顶管周围土体的变形影响规律.
Study on the Influence of Pipe Jacking Construction on Surrounding Soil Disturbance
In the construction of urban underground tunnels,the pipe jacking method is a relatively concealed underground excavation con-struction method,which has the effect of reducing road congestion,environmental pollution,etc.It has been widely used in practical engineer-ing today.During the construction process,it will have a significant impact on the surrounding soil,manifested as surface settlement and var-ying degrees of compression deformation of the soil around the tunnel.This article combines a pipe jacking construction project in the urban ar-ea of Suzhou,where the pipe passes under an existing transportation track.The main focus is on monitoring the displacement of the soil around Line 2 and analyzing the deformation impact of the soil around the pipe jacking.
