主　　题：Lade-Duncan failure criterion Rock damage Stress-strain curve Power function distribution Normal distribution 

摘      要：Based on damage mechanics theory,a rock statistical damage constitutive model is established based on Lade-Duncan criterion assuming that the rock damage variable follows either a power function distribution or normal *** parameters m and F0 of two version of the models were studied using variety of calculation *** two models are compared with experimental results to explore models’ applicability.
