摘要
目前超高层建筑深基坑面积大,深度深的工程越来越多,基坑临时支护结构与超高层建筑地下主体结构相结合已经成为上海软土出地区深基坑主要的发展方向之一。结合具体的工程实例,探讨超高层建筑地下主体结构与基坑支护结构相结合的设计与工程应用,包括利用地下主体结构型钢混凝土柱中的型钢钢骨作为临时竖向支撑立柱和底板范围内如何合理设置临时水平支撑等,并给出支撑轴力实测结果与计算分析结果,对主要的监测结果进行分析。
The temporary retaining and bracing system combined with substructure of high-rise building has commonly used in many larger and deeper foundation excavations. How to combine temporary retaining and bracing system with substructure of the actual construction project of a high-rise building was discussed. Computer model analysis and performance of the bracing structure results of instrumentation were presented. Performance of the wall based on the instrumentation results were also presented and discussed.
