分析合肥弱膨胀土地层的特点，其中合肥市 轨道交通 1 号线一、二期工程有 82% 处于膨胀土地层。 以合肥市轨道交通 1 号线葛大店站为设计实例，对合 肥弱膨胀土地层明挖车站结构设计方法进行阐述，可 为相关工程提供一定的参考。

This paper introduces the features of weak expansive soil in Hefei city. 82% of the phase 1 and 2 projects on Line 1 of Hefei metro will traverse the expansive soil. This paper takes Hefei metro Line 1 Gedadian station as an example and elaborates the station structural design.The station was embedded in weak expansive soil and built by open-cut method. The practice may be of help to similar engineering projects.
