摘要
介绍了某工程采用钻孔灌注桩联合止水帷幕加内支撑的复合支护技术的设计、工艺和施工,提出了当基坑开挖深度大于10 m时新的复合支护技术,并通过现场各项指标监测和施工任务评定,指出该施工技术的经济性、安全性,为高层及大跨度建筑深基坑支护技术提供参考和借鉴。
The design,process and construction of the composite support technology are introduced in an proj-ect which combines the application of bored piles and waterproof curtain with inner struct technology. A new compound support technology is proposed when the excavation depth is more than ten meters. Through testing indicators and assessing construction tasks,the economics and safety of the technology are pointed out to pro-vide reference for deep foundation pit support technology on high raise buildings and large-span construction.
