上海长峰商城逆作法施工中差异沉降的实测研究

Measurement Study of Differential Settlement During Reserved Construction in Changfeng Building of Shanghai

该文根据上海长峰商城特大型基坑逆作法施工中的实测资料,通过绘出立柱桩顶点在楼板各个施工阶段的等值线图,形象直观地反映基坑逆作法施工过程中立柱桩之间以及地下连续墙与相邻立柱桩差异沉降的变化情况,并对差异沉降进行分析和研究。

This paper is based on the measurement data of differential settlements, which are collected during reserved construction in Changfeng building of Shanghai. According to the settlement-contour maps of the floor supported by the top of soldier piles and continuous walls in each construction phase, the development of differential settlements between soldier piles and the development of differential settlements between diaphragm walls and adjacent soldier piles are directly reflected. Differential settlement is studied in this paper.
