摘要
上海环球金融中心主塔楼超深基坑工程,在直径100m圆形地下墙围护结构施工和土方开挖过程中,地下墙成槽区遇钢管桩,经采取成槽补强、降承压水、对称均衡开挖土方和信息化施工等,实现了超大直径圆形无支撑深基坑的安全施工。
For super deep foundation pit engineering for major tower of Shanghai Global Finance Center, when 100 m circular retaining wall enclosure and earthwork were constructed, trenching zone of retaining wall met steel pipe pile. Through trench strengthening, pressure water decreasing, symmetrical and balanced excavation of earthwork as well as information construction, secure construction to supper-diameter circular supporting-free deep foundation pit was realized.
