高敏感环境条件下基坑变形的精细化控制研究

Precise Control Research on Foundation Pit Deformation Under Highly Sensitive Environment Conditions

总结多年来上海地区数十个工程的实践经验,创新形成了包括2套施工工艺和2套变形控制系统在内的高敏感环境条件下深大基坑变形探测及精细化控制技术。通过在数个工程中的应用,证明了在软土地区采用深大基坑精细化控制技术能够有效控制基坑的变形,能很好地保证基坑周边保护目标和周围环境的安全。

Summing up dozens of engineering practice experiences in Shanghai over the years, we have innovated and formed a deep foundation pit deformation detection and precise control technology under two highly sensitive environment conditions including two sets of construction technology and two deformation control systems. Through the application in several projects, it is proved that the precise control technology for deep foundation pit can effectively control the deformation of the foundation pit in the soft soil area, which can well ensure the protection target around the foundation pit and the safety of surrounding environment.
