摘要: 本文将岩体中的宏观裂隙体视为岩体的一种初始损伤，给出了岩体的各向异性宏观损伤张量与裂隙间断位移引起的损伤应变张量，建立了以岩体体平均应力应变为基本变量的等效连续模型。同时，还讨论了如何通过现场工程地质调查，以获取确定岩体宏观损伤性质的工程地质信息。

Abstract: ln this paper,the macro一joint body in rockmass is described as an initial damage. The anisotropicmacro一damage tensor of rockmass is proposed .The damage strain is presented,which is caused by joint jump dis-placement. Its equivalent continuum model is established in which the main variables are volume averaging stress andstrain. ln the meanwhile,in order to obtain the engineering geological information for determining the macro-damage behaviour of rockmass,the survey methods in situ in engineering geology are discussed.
