The internal frame beams and frame columns of general subway station are important structural stress components. After being assembled in blocks, the structure joint connection needs to be reliable and have good integrity, so as to effectively transfer load. Although the large-span arched roof assembly subway station can increase the thickness of roof section without large amplitude, it needs to be arched, which not only increases the length of roof, but also generates excess space in the arch part. In addition, due to the arching of the roof of the large-span arched roof assembly subway station, the buried depth of the station bottom plate increases, and the water and soil pressure of the station structure increases, which is not conducive to the structural stress. The large-span variable cross-section roof assembly subway station uses a larger thickness at the position of side wall, and the thickness of the roof gradually decreases towards the middle part of the station, which adapts to the change of internal force of the roof.

The above-mentioned assembly subway station can obtain large-span space of subway station and produce unique architectural art effect, but there is still room for improvement in the buried depth of subway station and the structural stress of station structure.
