摘要
本文首先分析了盾构法隧道引起的地面沉降规律和沉降影响范围,总结了盾构隧道地面沉降的主要影响因素;指明地面沉降主要源于开挖面的应力释放和附加应力等引起的地层变形,并对地铁施工中的地面沉降安全判断标准和控制原则进行了探讨,为城市地铁工程建设提供有益的参考。
This paper analyzes the shield tunnel caused by land subsidence law and settlement of affected areas,and summarizes the main factors of land subsidence of the shield tunnel：specified land subsidence is mainly due to the excavation surface stress release and the additional stress causedstrata deformatlon,land subsidence and subway construction safety criteria and control principles are discussed to provide a useful reference for the construction of urban subway project.
