• Hitherto, perilous rock is the weakest topic in disaster studies. Specially, damage of con trol fissure under loads is one key technique in study of developing mechanism of perilous rock. Dam age division of end area of control fissure was defined, then calculation methods of timed-Poisson s ratio and timed-Young s modulus were established in damage mechanics theory. Further, the damage constitutive equation of control fissure is set up, which founds important basis to numerical simulation for control fissure to develop.
