高应变率下岩石损伤模型研究综述与展望

系统阐述了岩石爆破损伤模型的国内外研究现状,阐明了各自的理论基础和基本思想,并且作了简要评述,指出了各种模型存在的不足,对岩石爆破损伤模型的发展趋势提出了建议。随着弹性力学、断裂力学和损伤力学等固体力学在岩石破碎领域的广泛应用,以此为理论基础的岩石损伤模型必将会进一步得到发展和完善。

REVIEW AND PROSPECT ON THE RESEARCH OF ROCK BLAST DAMAGE MODELS UNDER HIGH STRAIN RATE

The development of the research on the rock blast damage models at home and abroad is presented;their theory basis and concepts are described.Attempt is made here to review the rock blast damage models in brief,pointing out the unperfect facts in the models.In the end,the author presents some tendencies of this study in the future.Along with widespread application of elastic mechanics,fracture mechanics and damage mechanics in the field of rock damage,the rock blast damage models will be developed and perfected.
