狭长深基坑半盖挖施工技术探究

城市地下开挖往往因场地的限制增加工程的难度.以上海诸光路通道新建工程为背景,依据“时空理论”对半盖挖法在狭长深基坑中的应用效果展开研究,并以围护结构与立柱的实测位移数据证明了其适用性,对今后类似条件下的施工具有一定的借鉴意义.

Research on Construction Technology of Half-cover Excavation of Long and Narrow Deep Foundation Pit

Urban underground excavation often increases the difficulty of the project due to site restrictions. Taking the new construction of Zhuguang Road in Shanghai as the background, the application effect of half-cover excavation method in long and narrow deep foundation pits is studied based on the space-time theory, and its applicability is proved by the measured displacement data of the enclosure structure and the column, which has certain reference significance for the constructions under the similar conditions in the future.
