摘　　要：介绍上海轨道交通9号线一期工程外环路站～合川路站区间,深31.9m、坑底位于⑦1承压含水层的虹莘路风井基坑工程设计以及开挖过程中一些关键问题的处理方法,提出关于钢筋混凝土支撑和坑底位于承压水层中基坑降水的一些建议。Introduced are the design works of excavation pit of the ventilation shaft, which is about 32m deep locating in the running tunnel between Outer Ring Road Station and Hu Chuan Road Station of Shanghai Rail Transit Line 9(1st phase). The excavation bottom is in the ⑦1 layer of artesian aquifer. And the key construction technology are also given out. Furthermore, some suggestions with regard to the reinforced concrete support and the dewatering method for excavation under artesian aquifer layer are proposed.

关 键 词：超深基坑 钢筋混凝土支撑 承压水
