Application of E.Hoek method to evaluating mechanical parameters of closely jointed rock mass——A case study of Baiyian Landslide in Three Gorges area;

The determination of strength and mechanical parameters of massive jointed rock mass is a difficult problem.

Based on analyzing challenging problems in the jointed rock mass confronting the smooth blasting technology, a new blasting technology, a two-direction energy-gathering blasting technology, is introduced for the jointed rock mass.

Study on Hydro-mechanical Behaviour of Rock Joints and Computation Method of Bolted Jointed Rockmass;

Scale effect on deformation characteristics of jointed rock mass based on numerical test;

Dynamic cluster analysis of discontinuity orientations of jointed rock mass;

Study on orthotropic equivalent strength parameters of jointed rock mass;

3-D network simulation and probability damage tensor analysis of joint rock mass in open iron mines;

Numerical simulating test on joint rock mass properties in Three Gorges Project;

Study on stress wave inverse model for jointed rock masses;

Preliminary research on 3-D hierarchical composite element method for jointed rock masses;

Research on ultimate load bearing capacity of foundation of jointed rock masses;

Orientation distribution of rock mass joints has been studied by scholars for about four decades,but the features of joint orientation distribution are still not easy to be described,because the orientation is distributed in the bivariate manner;and it is difficult to be used in the rock engineering.
