RELIABILTY ANALYSIS MODEL OF BLOCKY ROCKMASS STABILITY AND ITS APPLICATION
块状岩体的稳定可靠性分析模型及其应用

Based on mechanics classification of media,a reliability model for blocky engineering rockmass stability is made by mean of block theory and hemispheric projection. The stability probability of blocky surround rocks in a large underground opening is calculated according to the reliability model. The applying prospects and adaptation of the model are shown by project example.
