摘　　要：指出超大超深基坑工程是危险性高、影响因素众多的复杂系统工程,此类基坑工程的围护结构设计计算分析相关经验较少,围护设计存在很多问题。以上海世博地下变电站工程为例,阐述了该超大超深基坑工程的特点,通过国内某典型软土地基中超大超深基坑围护的实例设计分析,探讨了计算方法的选取,并对相关影响因素进行了分析。With high risks and various influencing factors, the ultra-large and ultra-deep foundation pit project can be considered as a complicated systematical project, and there is little design and calculative analysis experience of its retaining structure. Taking the underground Shibo Substation as the example, the features of the ultra-large and ultra- deep foundation pit project are analyzed. Through design analysis of one typical ultra-large and ultra-deep foundation pit in soft soil, the selection of calculation methods is discussed, and the influencing factors are analyzed.
