城市地铁隧道施工引起的地面沉降分析

Study on Land Subsidence Caused by Urban Subway Tunnel Construction

地铁具有运量大、准点、节省地面空间、环保等优势,因此近年来全国各大城市大力建设地铁工程。隧道作为地铁工程重要的部分,在施工时,很容易造成地面不均匀沉降,从而影响到周围建筑的安全。介绍地铁隧道施工的主要特点,分析城市地铁隧道施工引起地面沉降原因和影响,并针对地面沉降提出应对措施。地铁隧道施工时,必须结合实际情况,采取应对措施,避免地面不均匀现象的发生。

Subway has the advantages of large capacity,punctuality,saving ground space,environmental protection and so on,so in recent years,major cities in China have vigorously constructed subway projects.Tunnel as an important part of subway engineering,in construction,it is easy to cause uneYen ground settlement,thus affecting the safety of surrounding buildings.This paper introduces the main characteristics of subway tunnel construction,analyzes the causes and effects of ground subsidence caused by urban subway tunnel construction,and puts forward countermeasures against ground subsidence.Therefore,the subway tunnel construction,must be combined with the actual situation,take measures to avoid uneven ground phenomenon.
