摘　　要：以向家坝水电站VII坝址为例,讨论了三维地质建模的几个关键问题及其处理方法:①多源数据的整合方法;②采用Laplace插值点和原始数据点共同构造地质曲面的方法;③基于裁剪的近层状地质体的构造方法。展示了向家坝VII坝址三维地质模型在显示、自动成图、虚拟现实漫游和三维数值计算等方面的应用效果。With the fast development of computer technology, 3D geological modeling has been paid more and more attention by geoscientists. Taking VII dam site of Xiangjiaba Hydropower Station as an example, some key problems and their solutions with 3D geological modeling were discussed： （1） Integration method of multi-format data was put forward; （2） Constructing method of geological curve surface based on Laplace interpolating points and original points was proposed; （3） 3D modeling method of approximately layered geological body based on cutting was summarized. At the same time, application of 3D model of Xiangjiaba Hydropower Station, that is, its display, auto plotting, VR flying and 3D numerical analysis etc. were illustrated.
