Numerical tests of influence of heterogeneous random distribution on thermal cracking of rock;

Using random solid-heat coupled mathematical model and FEM,only considering thermal dilatability and thermal conduction as random variables,plane stain model is adopted to analyze the changes of thermal cracking of rocks caused by thermal stress;and the whole process of thermal cracking of rocks with Gaussian distribution and Weibull distribution laws is simulated.

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;
