					    摘要: 上海越江隧道端头井基坑属超深基坑工程,其围护形式及变形性状均同一般浅基坑有所不同,借助于基坑的监测数据,对深基坑的变形性状进行分析,并结合实际施工过程中出现的问题进行了探讨解释。为以后深基坑安全设计、施工提出相应的建议。Abstract: Working well of Shanghai crossing-river tunnel is a super-deep pit engineering. The enclosed structure and deform of pit is different from ordinary pit. According to monitor data , performance of deep pit is analyzed. Meantime, some problems in the construction are explained,which can provide reference to the design and construction of similar case.-
