Study on model experiment with multi-freezing-tube cycles and the mathematic model of moisture-heat coupling in frozen soil;

Numerical simulation and analysis of moisture-heat coupling for soft rock tunnel in cold regions;

Nonlinear analysis on moisture-heat coupling for rocks during freezing-thawing process;

Study on mine cracking by millisecond blasting in water coupling hole;

according to the similitude law of blast and the equations of shock wave in water , this paper searched the bore wall pressure of bore water coupling charge structure and established rocky dynamical stress field under the function of blasting load ,and then obtained the crack area radius , the pulverizing area radius and the best uncoupling coefficient of bore water coupling charge in theory.

Based on the excessive seepage water in the blasthole of the open mine's step of Bangmoshan, it is studied that using water coupling presplitting blasting to resolve the problem of slope presplitting blasting with water bearing blasthole.

Coal-bed methane percolation numerical simulation considering gas slippage and water-gas coupling;

The grid-based hydrological and silty model was developed on the basis of excess infiltration mechanism,considering the impact of structural measures for soil conservation on runoff routing.
