Rail transit structure and construction method thereof

The invention provides a rail transit structure and a construction method thereof, and relates to the field of underground engineering. The rail transit structure comprises a station, a connecting section and a shield section, wherein the station comprises a station body and a station air shaft communicating with the station body, the station air shaft is used for lowering a shield tunneling machine, one end of the connecting section communicates with the station body and is spaced from the station air shaft, the cross section of the connecting section is larger than that of the station body,the connecting section can allow the shield tunneling machine to pass, and the shield section communicates with the end, away from the station body, of the connecting section. The rail transit structure is beneficial to reducing the engineering excavation amount and improving the economical efficiency. 本发明提供一种轨道交通结构及其施工方法，涉及地下工程领域。轨道交通结构包括车站、连接段和盾构区间，车站包括车站主体和与车站主体连通的车站风井，车站风井用于下放盾构机；连接段一端与车站主体连通，与车站风井间隔，连接段的横断面大于车站主体的横断面
