摘要
上海市周家嘴路越江隧道浦东机架段基坑存在严重的单侧超载,令基坑围护变形不易受控,通过钢支撑自动伺服系统的应用,使基坑围护变形处于可控状态。以此为例,对该基坑在开挖过程中围护结构变形的相关情况以及相关特征进行总结与分析,为类似工程提供参考。
There is a serious unilateral overload in the foundation pit in Pudong frame section of the cross-river tunnel of Shanghai Zhoujiazui Road, which causes difficulty to control the deformation of foundation pit support. However, through the application of steel support auto-servo system, it makes the deformation of foundation pit support in a controllable state. Taking it as an example, the related conditions and characteristics of deformation of foundation pit support structure during excavation have been summarized and analyzed in this paper, which can provide references for similar projects.
