剪胀和接触面损伤是影响岩石节理和其他地质结构面行为的重要现象。包含这些行为的有效本构定律最近得到了发展，但需要规范新的材料参数来控制粗糙表面的损伤。确定控制损害的参数是目前从业者面临的一个难题。本简报将总结Hutson和Dowding对节理表面粗糙度退化的调查结果，并详细说明应用的含义。
Dilatancy and contact surface damage are important phenomena affecting the behaviour of rock joints and other geological discontinuities. Effective constitutive laws that incorporate these behaviours have recently been developed but require the specification of new material parameters that govern damage of asperity surfaces. Determination of the parameters that control damage is currently a difficulty that confronts practitioners. This brief will summarize the findings of Hutson and Dowding's investigation of joint surface asperity degradation and elaborate on the implications for application.
