摘　　要：深基坑开挖是一项非常复杂的工程,在设计和施工中,不仅要考虑基坑支护结构本身的安全与稳定问题,还应该考虑地下水对基坑稳定性的影响以及岩土体工程性质的复杂性。以南京某深基坑工程为对象,对深基坑及其围护结构选型进行了分析,总结了深基坑围护设计中关键的计算与验算内容。对比分析了设计计算结果与实际监测数据结果,证明了所采取的围护形式的有效性,可为以后类似工程提供一些借鉴。The excavation of deep foundation pit is a very complex project, in the design and construction of foundation pit, should not only consider the security and stability of retaining structure, should also consider the effect of groundwater on the stability of foundation pit and the complexity of the engineering properties of rock and soil. In a foundation pit in Nanjing as the object, the se- lection of deep excavation and retaining structure is analyzed, summarized the key calculation and checking the content design of retai- ning of deep foundation pit. Finally comparative analysis of the calculation results with the monitoring data show the effectiveness of the results, the envelope form, can provide some reference for future similar project.
