摘　　要：以北京新建王府井车站洞桩法施工工艺为研究对象,设计出符合施工特点的沉降观测方案。针对观测数据动态变化大、数据量大等特点,采用SPSS数据分析软件对其分析,并提出了符合上述施工特点的沉降回归模型,分析了地铁开挖引起的地表沉降规律。结果表明,越靠近施工竖井和横通道,沉降值越大,且沉降值呈抛物线趋势。Taking the construction technology of Wangfujing subway station in Beijing as the research object,the settlement observation scheme conforming to the construction characteristics is designed.In view of the characteristics of large dynamic change and large amount of observed data,SPSS data analysis software was used to analyze the data,and a settlement regression model consistent with the above construction characteristics was proposed to analyze the law of surface settlement caused by subway excavation.The results show that the closer to the construction shaft and the cross passage,the greater the settlement value,and the settlement value shows a parabolic trend.
