摘要
深基坑支护工程是一项非常复杂的工程,不仅要考虑基坑围护结构本身的安全性与稳定性的问题,还应该考虑基坑开挖对周边环境的影响。以软土区某深基坑工程为对象,根据场地的土质条件、周边环境情况及基坑规模等对深基坑围护结构选型进行了分析,提出设计过程变形控制及施工过程变形控制的技术要求。最后对基坑的实测数据做了分析,结果表明,所采取的变形控制措施有效地保护了基坑周边环境。
The excavation of deep foundation excavation is a very complex project. It is not only to consider the safety and stability of foundation excavation retaining structure,but also should consider the influence of foundation excavation on the surrounding environment. A foundation excavation in soft soil area as the object,the selection of retaining structures are analyzed according to the soil condition,the surrounding environment and the size of foundation excavation. The technical requirements of deformation control are proposed in design and construction process. Finally,the monitoring data of foundation excavation is analyzed,the results show that the deformation control measures are effective to protect the surrounding environment of foundation excavation.
