Analysis on the process of water burst catastrophe and it s prevention countermeasures in a karst tunnel;

Influence of long-term draining groundwater in karst tunnel on permeability of its surrounding rock;

Risk management of Karst tunnel of Yichang-Wanzhou Railway

Discussion on influence of initial support to stability and deformation of surrounding rock mass in soft rock tunnel;

Determination of soft rock tunnel frost heaving damage parameter;

The results of the analysis on the deformation characteristics, damage shapes and collapse height of soft rock tunnels indicate that the Hoek-Brown\'s brittleness parameter method is a practical and reliable approach of predicting the collapse height of a tunnel in soft rocks.

Review of research on instability failure mechanism and stability control of tunnel surrounding rock in water-bearing sandy ground

A comprehensive study of tunnel surrounding rock classification methods

In regard to resistance,the rule of setting the maximum allowable deformation which is applicable to all kinds of tunnel surrounding rocks is studied.

The application of matter-element extension model in stability classification of surrounding rock of tunnel;

According to the characteristics of engineering geology and support design in weak rock tunnel, a finite difference method for fast lagrange analysis code(FLAC) was applied to simulate the deformation characteristics and convergence curves of weak rock tunnel in the paper.
