摘　　要：在复杂的城市地下工程施工过程中,对施工引起的围岩及结构变形进行控制是决定施工成败的关键因素之一。北京铁路枢纽北京站至北京西站地下直径线工程ZJX-2标施工过程中,通过对盖挖法和CRD法各阶段施工引起的围岩及结构变形进行监测,系统分析地层与结构变位及两种施工方法之间的关系,总结出两种施工方法引起的围岩及结构变形规律,对指导施工、控制围岩及结构变形起到很好的作用,使施工始终处于可知可控状态。It is the critical factor to control deformation in the complex construction process of urban metro. By monitoring the deformation of adjacent rock and structure due to excavation cap method and CRD method construction, the relation between deformation of adjacent rock and structure is analyzed systematically, and the regularity between deformation of adjacent rock and structure and two job practices is summed up. Consequently it is helpful to instruct construction and control deformation of adjacent rock and structure.
