真三维地学模拟系统与水利工程应用

Real 3D Geosciences Modeling System and Its Applications in Hydraulic Engineering

水利工程涉及工程地质与岩土开挖问题,在场址选择、渠涵选线、工程施工、沉陷与变形监测全过程中,需要一系列的地质调查、工程勘察、围岩结构及其稳定性分析基础工作。真三维地学模拟的主要目的是基于钻孔数据并综合地球物理与地球化学等多源地学数据来建立研究区域的集成地学空间数据库,并利用真三维体元来构建研究区域的数字化的真三维地层环境模型,从而在可视化环境中实现地层任意剖切、量算、揭层显示和开挖设计,以及各类地学统计、查询与空间分析。该文以煤矿地质环境建模为例,介绍了国产真三维地学模拟系统GeoMo^(3D)的基本功能,进而分析了GeoMo^(3D)在南水北调工程中的应用前景。

Hydraulic engineering is a typical issue of engineering geology and rock - soil excavation, it relates to a series of fundamental works including geological investigation, engineering investigation, strata structure and stability analysis in the process of site selection, canal - tunnel alignment, engineering construction, subsidence and deformation monitoring. The goals of the real 3D geosciences modeling is to build a integrated geo - spatial data base of drillholes, geophysical data, geochemistry data and so on, and to construct a real 3D digital model for the geological environment of site region based on volumetric primitive. Then, the section - generation, spatial measurement, uncover visualization, excavation design, geostatistics, geo - spatial inquiry and analysis can be conducted in the visualized 3D geosciences model. With a case of a coal mine, the chief functions of a developed real 3D geosciences modeling system with ourselves copyright, GeoMo3D, is introduced. The possible applications of GeoMo3D in hydraulic engineering, especially in the great engineering of Transfer Water from The Southern to The Northern, is analyzed.
