However, during the construction of Kuocangshan tunnel, rockburst occurred in two relatively shallow areas (under 250 meters), and not in the most deeply position.

According to data from more than 2 100 drill holes,lithofacies, 14 C dating of sediments,field investigation,distribution regularities,buried situation and sedimentary characteristics of the shallowly buried paleochannel zones in the south coast plain of the Laizhou Bay, its stage divisions and development laws have been studied.

Construction technique for opening section of shallow buried water conveyance tunnel;

Scattering of SH-wave by a shallow buried elliptic cylindrical cavity and dynamic stress concentration;

The first weighting procedure of shallow buried face under thin bedrock may be divided into 3 phrases: lower strata caving,key strata and its upper strata's damage and caving,lagged caving of loose strata.

A Brief Introduction to Design &. Construction of Shihuang Tunnel with Shallow Overburden;

Based on the principle of New Austria Tunneling Method,the Cross Diaphragm Method is usually selected to construct big-span shallow overburden highway tunnel.

In this paper,with the rectangle tunnel construction in the foreland soft rock with shallow overburden,FLAC is adopted to simulate the excavation of tunnel using partial excavation method,The mechanism of large deformation process of rectangular tunnel primary support is studied.

Study on excavation sequences and support optimization for shallow-buried and large-spanned tunnels;

Simulation on different excavation construction of the shallow-buried tunnel under the uneven rock pressure

With the Longtan Tunnel of the Shanghai-Rongxi Expressway as an example, the paper outlines the complex geological conditions of the shallow-buried and biased tunnel, and introduces the slurry-reinforcing technique used for the ground of the inlet section of the tunnel, the key construction techniques for the inlet section, and the reinforcing measures against deformation.
