RELIABILTY ANALYSIS MODEL OF
BLOCKY ROCKMASS STABILITY AND ITS APPLICATION
|
|
|
|
|
Abstract 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.
