Abstract

Heterogeneity of rocks has a great influence on macroscopic mechanical behaviors. So in rock mechanics research, the heterogeneity should be described properly. This paper presents Weibull distribution, which can describe the microstructure parameters heterogeneity, and sums up heterogeneous parameter’s influences on the failure process, macro-strength and rock burst. Then random parameters assignment method of rock mineral cell unit is presented, and the influences of heterogeneity on macroscopic mechanical behaviors are showed. Combing digital image processing with numerical simulation software, the new method of building actual microstructures model of rocks is presented.
