谈有限空间内深基坑工程支护技术

Discussion on supporting technology of deep foundation pit engineering in limited space

以中央戏剧学院工坊项目深基坑工程为研究对象,对场区的地质条件、周边环境对有限空间内深基坑支护的影响进行了分析。提出了有限空间内深基坑支护的注意事项及整体方案,采取了监测手段对支护结构及周边建筑物的变形进行动态监测,为今后类似深基坑工程建设提供参考。

Taking the deep foundation pit project of the Workshop project of Central Academy of Drama as the research object,the influence of the geological conditions and surrounding environment of the site on the support of deep foundation pit in the limited space was analyzed.In this paper,the matters needing attention and the overall scheme of deep foundation pit support in limited space are put forward,and the deformation of supporting structure and surrounding buildings is dynamically monitored by means of monitoring,which provides reference for similar deep foundation pit construction in the future.
