摘要
带约束的Delaunay剖分算法多应用于表达数字地面模型,用于三维地质模型的构建尚不成熟。为了直观显示工程地质结构和快速准确分析工程地质条件,可依据带约束Delaunay三角剖分算法分别生成地层、断裂、界线类地质结构的TIN模型,拼合形成工程整体三维地质模型。通过编制基于TIN模型的工程三维地质建模程序,建立了金沙江两家人水电工程坝址区域的三维地质模型,为工程地质评价及工程设计提供了决策支持,以此作为工程应用实例。实践应用表明,该方法具有快速、准确、通适的特点。
For directly displaying engineering geological structure and accurately analyzing engineering geological condition, Delaunay triangulation algorithm was applied to make geological structure TIN model such as geologic strata, faults, boundary etc., and then they were merged together to combine the whole engineering 3D geological model, and this method is fast, accurate and general. Through making the program of modeling 3D geological, the 3D geological model of Liangjiaren hydro-power project, which locates at Tiger Leaping Gorge in Jinshajiang River, was built as a sample, and decision support for engineering geological evaluation and engineering design was provided.
