【Abstract】 Mechanical characteristics of rock,concrete materials and structures are described.State-of-the-art numerical modeling and methods for analysis of rock and concrete structures are summarized.The scientific and technological frontier issues are reviewed;and case studies of employing discrete-contact-fracture analysis models for safety evaluation of high dams and foundations are accomplished.Finally,it is pointed out that the prospect of development for rock and concrete is to construct a unified numerical model of combining continua and discrete media.Thus,analysis of rock and concrete starting from damage initiation in meso-scale(even micro-scale) to complete process of rupture in macro-scale can be performed.更多还原
