摘　　要： 本文通过对沈阳北站Ⅰ区人防工程深基坑的围护桩顶水平位移、桩侧土压力、混凝土支撑轴力、临时立柱桩隆起以及基坑周边地表沉降、坑外地下水位变化、周边管线沉降、周围建筑物沉降的系统监测,探讨了复杂条件下基坑开挖期间支护结构及周边环境的变形规律。为本地区同类工程施工提供参考依据。 In this paper, through the system monitoring of horizontal displacement of pile foundation, the pile side earth pressure, the concrete supporting axial force, the temporary pillar pile uplift and the foundation subsidence of the foundation pit, the change of the groundwater level outside the pit, the settlement of the surrounding pipeline and the settlement of the surrounding buildings of the deep foundation pit in Shenyang North Station I Region air defense works, the deformation law of the supporting structure and surrounding environment during excavation under complex conditions is discussed, to provide reference for the construction of similar projects in the region.
