The paper gives a brief introduction to the major principle and technology of construction of submerged tubular tunnels and the present situation of submerged tubular tunnels in various countries and regions in the world.

A shoring structure of the subsidence-style tunnel is designed based on symmetrical load.

Applying mechanism and analysis method of anchored-bolt pre-reinforcing surface of shallow tunnel;

Design of Shallow Tunnel with Quadruple Arches;

The statistical characteristic of the break angles by excavating the shallow tunnel;

Influences of stress dilatancy on stability factors of shallow tunnels;
