The deformation behavior and construction technology of the shallow-buried sandy stratum tunnel have been the research focus in the Geotechnical engineering field due to its difficulty to construct, large deformation and poor stability.

A Research over Construction Technology for Large Section Shallow-buried Tunnel on Mollisol Tier of Urban Subway;

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;

Geological condition of shallow-buried tunnel is complicated.

Based on an engineering case,the mechanism of the pre-support system applied in treatment for the collapse of shallow-buried tunnel is discussed.

The impact of excavation of shallow-buried tunnels on the surrounding environment is worthy of attention.

This paper introduces the Geological conditions and surrounding environment of a certain city s shallow buried tunnel engineering, expounds the features and concrete measures of the quick tunneling construction technique, and points out that the meticulous organization and scientific management are the effective guarantees for realizing the quick tunneling of the urban tunnel.
