摘    要:
传统的岩体质量评价体系不考虑或仅从破坏角度考虑地应力的影响.为了反映岩体损伤演化过程,针对深部岩体在自重应力场和构造应力场的作用情况,提出地应力的修正计算方法;根据Mohr-Coulomb准则,引入破坏接近度的概念,提出修正地应力造成的岩体损伤评价方法,并与岩体损伤破坏评价5个等级对应,建立了Q值与岩体损伤等级对应关系.

关 键 词:地应力  岩体损伤  应力场

Abstract:
The traditional evaluation system of rock mass quality does not take into consideration of ground stress effect,or it only consider the failure of rock mass.In order to reflect the procedure of rock mass damage,the ground stress revised method is proposed for the situation of deep rock mass under the load of gravity and structural stress;then,according to the Mohr-Coulomb criterion,the concept of destruction approaching degree is introduced to promote the evaluation analysis for the rock mass damage based o...
Keywords:ground stress  rock mass damage  stress field
