摘要
侨福花园广场基坑开挖约22 m,采用上部土钉墙和下部锚拉桩(墙)结构,下部支护的土方开挖会对上部土钉墙位移产生一定的影响,对项目进行了全阶段的现场监测,分析基坑顶部水平位移变化规律,对北京地区类似工程可起一定的借鉴意义。
Qiaofu plaza project with its excavation depth about 22m ,the retaining system of which is composed by soil nailing wall on upper side and piles（or diaphragm wall） supported by anchor on lower side. The horizontal displacement on top of the foundation pit must be influenced during the lower excavation. In this project, on-site monitoring is taken during the whole excavation, the displacement changing law has been analyzed. It will be useful later in Beijing.
