摘　　要：为提高盾构隧道施工技术水平,控制地表沉降,本文以广州地铁四号线北延段车陂至南村站区间盾构隧道工程为背景,分析了盾构隧道引起地表沉降的主要施工参数并进行了相关的优化,通过分析地表沉降的时间规律,研究提出了控制盾构掌子面、盾体通过和盾尾脱出时三个阶段地表沉降的可行技术工艺。In order to raise the shield tunnel construction technique level,control the ground surface settlement,this article uses the Guangzhou subway 4 line north extends section Che-Huang station sector as engineering background,analyzes the shield tunnel main construction parameter cause the surface subsidence, summers and optimized the construction parameter. Through analyzes the time rule of surface subsidence,this article proposes the feasible technical craft to control surface subsidence including the shield face,the shield body through and the shield tail leaves.
