The paper makes a full analysis of rock mass characteristics、rock mass structures and rock mass behaviors in unloading fracture zone with a key water control project.

Combined with the construction of anchor cable on the slope of TGP抯 permanent shiplock,the rockmass properties near anchor is studied after being prestressed.

Numerical modeling of flexural deformation of laneway in layered rock mass;

Deformation of huge underground opening excavated in layered rock mass with steep dip angle;

Stability analysis and anchor methods for blocks of underground layered rock mass in cavern excavation;

Study on integration of three-dimensional modeling and numerical simulation for stratified rock mass;

Excavation response of tunnel in stratified rock mass based on Hoek-Brown criterion

A definition of water-inrush-factor was presented,and the criterion about the instability of seepage flow of water in stratified rock mass was described by water-inrush-factor.

The mechanism analyses of bedded rock blasting damage and fracture;

Model study of seepage in single fissure bedded rock;

Study on the shearing strength mechanical characteristics of bedded rock

Numerical simulation of excavating openings in layered rockmass considering the couple stress;

The physico-mechanical characteristics of layered rock are different between its tangential and normal orientations.
