Experimental and theoretical investigations of electromagnetic radiation induced by rock fracture;

This paper describes the Analysis System RFPA2D in process of rock fracture, which applies in investigation of moving rules of rock, and conducts calculation of actual instance.

The fractal structure of rock fracture in dam foundation of the Three Gorges Project under uniaxial compression is studied based on fractal theory.

Study on coupled thermal-mechanical-damage model in rock failure process;

Aelocation method based on neural network and the application in tests on rock failure;

Study on simulation of statistical damage in the full process of rock failure;

There are many omens existing before rock fracturing,which is an important research issue of rock mechanics and rock engineering.

The correlatives of the electromagnetic signals emerged before and after earthquake and rock rupture is observed and measured, in which the results make known that the phenomenon and information exist objectively and will become the basis for seismic forecasting research.

The comparison between the indication of acoustic emission and remote sensing before rock rupture was made.

Testing study of gas permeability of fracture rock under peak stress;
