摘要
EVS地质建模平台可实现真三维的地质体建模、分析及可视化,提供了克里金法、自然邻点法、最近邻点法等7种空间插值方法,支持矩形线性网格、有限差分网格、凸包网格等4种网格类型。本文系统介绍了EVS地层建模、岩性建模、混合建模等构造建模及属性建模的方法及流程,总结了各类建模方法的适用地质条件,为EVS在三维地质建模中的应用提供技术参考,推进了地质BIM技术的发展。
The EVS-based geological modeling platform can realize true three-dimensional modeling,analysis and visualization of geological bodies.It provides seven spatial interpolation methods(kriging method,natural neighbor method,the nearest neighbor method,etc.)and supports four types of grids(rectangular linear grid,finite difference grid,convex hull grid,etc.).This paper introduces systematically the methods and processes of structure modeling and property modeling(such as EVS-based stratum modeling,lithology modeling and hybrid modeling),summarizes the applicable geological conditions of various modeling methods,and provides technical reference for the application of EVS in 3D geological modeling,aiming to promote the development of geological BIM technology.
