地铁隧道施工中地表沉降原因及控制技术——以浅埋暗挖地铁隧道工程为研究对象

Causes and Control Techniques of Ground Subsidence in Construction of Metro Tunnels--Take the shallow-buried and concealed subway tunnel project as the research object

地铁隧道建在城市地表之下,隧道施工必然会对周围土体产生扰动,导致地表沉降,将会对城市居民的生命财产安全以及地铁工程质量造成严重影响。所以在进行城市地铁的施工时,要对沉降进行严格的控制。文章分析产生地表沉降的原因,提出对地表沉降进行有效预防的措施以及在沉降较大时如何进行有效治理。

A subway tunnel is built under the urban surface.The tunnel construction will inevitably disturb the surrounding soil and cause ground subsidence.It will cause serious loss of life and property safety for urban residents and the quality of subway engineering.Therefore,in the construction of urban subways,it is necessary to strictly control the settlement.This article analyzes the causes of surface subsidence,and proposes effective prevention measures for surface subsidence and how to effectively control them when the settlement is large.
