摘要
上海地区处于淤泥质软土地质条件下。轨道交通8号线延吉中路站在施工过程中 ,临近的延吉七村 6号楼产生了较大差异沉降。通过对延吉中路站基坑施工期间各种施工参数及 6号楼的沉降规律分析 ,推断出较大差异沉降的根本原因是 6号楼局部座于低强度、高灵敏度的暗浜之上。提出采用注浆、基础托换等对策 。
In the construction of Metro Line 8 in Shanghai,large difference settlement of a building is found near the metro deep bed pit.This paper analyzes the various construction parameters of the pit and the settlement pattens of the building,then argues that the reason of the settlement is the silt under the building,which has lower sustainability but higher sensitivity.Therefore,the only solution is to replace the base of the building.
