摘要： 在富水地区城市主干道十字交叉口正下方，根据现场监测情况，通过验算并结合相关工程的经验，利用既有地下二层车站的围护结构，在不新增地下三层结构对应的围护结构前提下，采取相应的加固措施并进行抽条分块开挖，顺利完成三层换乘节点，取得了较好的实践效果，可为今后同类工程设计与施工提供一定的参考。

Abstract: A threestory subway transfer junction is constructed underneath the main intersection of the city's main streets in the high groundwater area. The supporting structure is the same structure for the two story station deep excavation. The segmental strip excavation was used during the construction without increase the depth of the existing supporting structure. This paper presents the design and construction considerations.
