中顺边逆法在深基坑基础中的应用

Application of Middle-clockwise and Side-anticlockwise Method in Foundation of Deep Foundation Excavation

仁恒海河广场一期公建项目位于天津市海河沿岸,由于该项目地理位置特殊、周边环境复杂且与地铁出入口相连、基坑面积大、深度深,使得该项目地下工程的施工较为复杂,该工程采用"中顺边逆"施工方法,在保障基坑安全的同时加快了施工进度。对"中顺边逆"的施工工艺流程及主要施工节点的处理方法进行了详细介绍。

Yanlord Riverside Plaza as a public construction project is located in Tianjin Haihe River coast,due to the location of the project with complex surrounding environment and the subway entrance is connected,foundation excavation with large area and depth,the construction of the underground project is more complex. The middle-clockwise and side-anticlockwise method is adopted in the project,which ensures the safety of the foundation excavation and accelerates the construction schedule. The construction process and the main construction node processing method of middle-clockwise and sideanticlockwise method are introduced.
