摘　　要：在介绍VJC-RMR法(Volumetricjointcount-rockmechanicsratingmethod)基本原理的基础上,对贵阳市鱼简河水库坝基岩体进行了质量评价和变形模量确定,并与原位试验法、Q法(Rockmassquality)和岩体损伤的分形模型(Fractionalmodelofrockmassdamage)进行了比较。结果表明,VJC-RMR法能够将一维问题转化为三维问题,更好地反映岩体的实际情况,是进行岩体质量评价和参数确定较好的一种方法。Based on introducing the principle of VJC-RMR method (Volumetric joint count-rock mass rating method), rock mass modulus of deformation and quality of dam foundation of Yujianhe Reservoir in Guiyang City are evaluated and compared to in-situ test, Q method (Rock mass quality) and fractional model of rock mass damage. The results show that the VJC-RMR method is a good method for evaluating rock mass quality and determining rock mass parameters. The method can reflect real condition and transform one dimension into three dimension.
