摘要
着重介绍了上海环球金融中心塔楼100 m直径圆形无支撑大型深基坑施工技术,在100 m直径圆形深基坑施工过程中,综合运用了超深地下连续墙、降承压水、岛式和对称、均衡、分层开挖等施工技术以及碰桩区地下墙补强、电梯井围护方案优化等措施,并结合全过程信息化监测,保证了超大直径圆形无支撑深基坑施工和周围环境的安全。
The self-sustaining structure construction techniques for the tower of Shanghai World Financial Center with 100 m diameter-circular were introduced. During the deep excavation construction of 100 m-diameter circular, many comprehensive techniques and measures were applied, such as super deep diaphragm walls, pressure water, island style, symmetry, proportion, delamination excavation, diaphragm wall strengthening in touching stake area, defendirig project optimization of elevator well and so on. Meanwhile, the whole process information inspection was employed to ensure the safety of super large diameter circular self-sustaining deep excavation construction and ambience.
