摘要
三维地质建模是实现地质信息可视化的一种重要手段。通过收集、分析北京市潮白河冲洪积扇地质及水文地质资料,开发运用ArcGIS软件的三维可视化应用程序ArcScene,对钻孔数据进行样条插值,采用基于面的建模方法建立了潮白河地下水库三维地质结构模型。同时,在此基础上,利用ArcScene中的Animation工具条,通过控制潜水面的升降模拟地下水库补给与消耗的动态变化,建立地下水库动态模拟展示模型。模型形象地展示、模拟了研究区地下水库地质结构特征及地下水库补给与消耗的动态变化特征,为地下水库的分析与建立提供技术支持,且为以后利用ArcScene进行三维地质建模提供依据。
Three-dimensional geological modeling is an important means for geological information visualization. Through collecting and analyzing the geological and hydrogeological data of alluvial fans of the Chaobai River in Beijing, this paper established 3D geological structure model of groundwater reservoir of the Chaobai River based on surface-modeling method by using 3D visualization application ArcScene of ArcGIS software. At the same time, on this basis, by using the Animation toolbar in ArcScene, the model showing dynamic simulation of groundwater reservoir was established. The model vividly displayed the geology structure characteristics and the dynamic characteristics of recharge and consumption of groundwater reservoir in the study area. The result provided technical support for the analysis and establishment of groundwater reservoir and basis for establishing three-dimensional geological modeling by using Arc.Scene in the future.
