Abstract：At Linjiangmen station of Chongqing Light Rail Project，the excavation width of the main structure is 23.040 m，and the height is 50.578 m. But the smalless thickness of cover rock masses is only 10.5 m. It is a super-shallow-berried single-span tunnel project. The New Austrian Tunneling Method is used in design of station，constant-section composite lining is employed for the station structure；and the construction technique of double-side-drift buried excavation is adopted. The structure design and construction scheme are studied，in which the geologic condition，main structure and construction difficulty are expounded.
