摘要：
An elastic damage constitutive equation based on initial flexibility tensor and damage evolution of rock mass considering hydraulic pressure is developed. A concept of additional hydraulic pressure-induced flexibility tensor is introduced to indicate the influence of hydraulic pressure on the mechanical characteristics of fractured rock mass. The results obtained from theoretical analysis show that the influence of hydraulic pressure on initial damage and damage evolution could not be ignored when there is fluid flow in rock mass.
