摘　　要：由微分几何学基本原理得出构造面主曲率和Gauss曲率的一般计算公式,利用曲率的几何意义进行地质构造面的形态和弯曲变形程度分析,并做为裂缝发育预测的评价因子。而且将微分几何学、数值分析、图形学和三维可视化技术相结合开发了地质构造面曲率分析及三维可视化软件3DCAVF。软件实现的主要功能有:构造面的主曲率和Gauss曲率的分析计算,对构造不同区域的变形形式、程度进行分析,以及地质构造面、计算分析结果的三维可视化、切片显示和等值线云图显示。并成功应用于裂缝油气藏研究。This paper obtains the general expressions of the principal curvature derived from differential geometry and use the geometry meaning of curvatures to analyze the shape and the extent of deformation of structural surfaces. The bend extent of structural surfaces was taken as one factor for the forecasting of cracks,and the software_3DCAVF was designed for curvature analysis and 3D visibility. The main functions of the software were as follows: the calculation and an alysis of the curvatures of structural surfaces, the analysis of deformation styles, contour and 2D/3D visibility of structural surfaces and analyzing results. It has been applied to the research of the crack oil_gas resources.
