Study on the Inverted Construction Method of Especially Big Pit Considering the Interaction Between Foundation and Structure
-
摘要: 考虑到施工过程中对基坑底部回弹量和差异沉降量的明显减小,逆作法目前取得了较广泛的应用。在基坑开挖过程中考虑基础和上部结构的共同作用,可以有效地控制基坑变形。通过对一个特大基坑的实测分析,简要说明了共同作用理论在逆作法施工中的具体应用。Abstract: Considering the obvious decrease of the pit bottom bounce capacity and differential settlement, the inverted construction method is widely used. It can validly control the distortion of pits, thinking over the interaction between foundation and upside structure in pit digging. The applications of interaction theory in inverted construction method is indicated by analyzing one example of an especially big dip.
