基于arcengine和钻孔数据的三维地表层建模与可视化
DOI: 10.3969/j.issn.1000-2006.2013.04.026, PP. 139-142
Keywords: 地层信息,arcengine,钻孔数据,三维可视化,建模
Abstract:
钻孔是获取地层信息最直观、准确和详细的手段,地层的内部构造可以通过钻孔信息应用三维建模方法表达出来。为了保证隧道施工安全,实现盾构隧道顶部地表层的可视化,提出了一种基于钻孔数据构建三维地层模型的方法:首先应用arcengine对钻孔数据进行预处理,得到钻孔的空间信息;基于三维约束delaunay四面体化算法和预处理后的离散钻孔信息构建ten(四面体格网)模型;在arcengine的平台调用数据库中的钻孔数据、地表层属性等信息,实现地表与钻孔信息的三维显示、信息查询和地层分析等功能。
