| 摘 要： | 提出基于钻孔数据和交叉折剖面约束的三维地层建模方法,解决了单纯基于钻孔数据建模方法中无法控制钻孔间复杂的地质现象等问题.在该方法中,还利用道格拉斯一普克(Douglas-Poiker)矢量曲线抽稀算法对交叉折剖面中的矢量地层曲线进行了处理,消去了光滑曲线上对模型质量无影响的密集顶点,避免了在剖面线处Delaunay三角剖分出现过多非正三角形,从而提高了整个模型的精度.在"杭州市城市地质信息管理与服务系统"中应用该方法取得较好的效果.

| Abstract: | In this paper,the three-dimensional geological modeling method based on drilling data and constraints of intersected folded cross-sections was put forward.Some problems were solved such as the control of complex inter-geological phenomenon in drilling data,which is out of control based on the simplex drilling data.In this method,Douglas-Poiker dilution algorithm for vector curve is used for dealing with vector stratum curve in intersected folded cross-sections and eliminating points which are no effect on t... |
