以上海世博央企总部基地高密度街区群坑工程为背景,结合其中3个同期施工基坑的监测数据,分析了群坑同期施工过程中的围护墙变形、围护墙顶部位移、支撑轴力和立柱竖向位移的变化规律,分析结果表明:与基坑普通位置相比,群坑相邻侧的围护墙变形减小,围护墙顶部位移减小,立柱隆起增大,相邻基坑的开挖深度越大,该方向的支撑轴力越小。 Based on the high-density block cluster project of Central Enterprise Headquarters in Shanghai World Expo 2010 and the monitoring data of three corresponding construction pit during the same period, the deformation of the retaining wall, the displacement of the top of the retaining wall, The results show that the deformation of the retaining wall on the adjacent side of the group pit decreases, the displacement of the top of the retaining wall decreases, the uplift of the column increases, and the adjacent base The greater the pit excavation depth, the smaller the support axial force in this direction.
