摘　　要：基于数据库的三维地质建模已广泛应用于地质勘测领域,本文以南山口抽水蓄能电站为例,展示利用CnGIM_ma三维地质软件构建的地下厂房围岩的三维模型,并通过对围岩进行等级分类准确评估其力学参数。结果显示,利用三维模型能更准确地反映岩体的真实条件,为地下厂房的建设及开发提供参数基础,并及时呈现地质信息成果。Geological 3D modeling basing on databases has been widely used in geological exploration.In this paper,we will use the CnGIM_ma 3D geological software to build a 3D model of the surrounding rock of the underground power plant at Nanshankou pumped-storage power station as an example,and accurately classify the rock mass grade to evaluate its mechanical parameters.The results show that using a 3D model can more accurately reflect the true conditions of the rock mass,providing parameter basis for the construction of the underground power plant and the development of geological information.
