How to choose the shape of the section?

The reasonable shape of the alley is to make the structure in a good stress state under different formation pressure conditions. It can ensure the safety of the roadway and the most economical materials, and at the same time, the section excavation works are the least and easy to construct.

It is now generally considered that an elliptical arch is a reasonable shape of a roadway, followed by an arc arch.
