摘    要:危岩是迄今研究程度极其薄弱的地质灾害类型,而主控结构面受荷损伤是危岩发育机理研究的核心技术.通过定义主控结构面裂端损伤区,运用损伤力学方法建立了裂端损伤区的即时泊松比和即时弹性模量的计算方法,并据此构建了主控结构面裂端损伤本构方程,为主控结构面断裂演化数值模拟奠定了理论基础.

关 键 词:危岩    主控结构面    损伤区    损伤模型    应用

Abstract:Hitherto,perilous rock is the weakest topic in disaster studies.Specially,damage of control fissure under loads is one key technique in study of developing mechanism of perilous rock.Damage 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.
Keywords:perilous rock  control fissure  damage area  damage model  application
