|
Abstract The extension method is introduced in this paper，and the matter-element model for evaluating surrounding rock stability of underground engineering is established. The research indicates that the extension method is reasonable and feasible in evaluating surrounding rock stability，and it can well reflect every evaluating factor’s influence on surrounding rock stability. The factor weight is determined by using simple dependent function，and this can avoid the effect of subjective factor of human in practices.
