地下水流场三维流线分布可视化研究及应用

 研究区地质条件的复杂性与三维流线的视觉叠加性在一定程度降低了三维流线图的可读性。通过分析地下水流线的生成过程,将其分布控制归结为流线初始点的布置问题,在探讨地下水流场特征点的基础上,结合流线初始点局部布置方法,制定了流线初始点的整体布置原则。以内蒙古自治区鄂托克前旗上海庙矿区鹰骏一号井田为例,利用其水文地质资料对流线布置原则进行检验,获得的流线图清晰地描述了地下水运动规律且有效地揭示了地质特征点(天窗)对地下水径流的控制作用,证明了流线布置原则的合理性与有效性。

Three-dimensional visualization of streamline placement for groundwater flow field: Research and applications

The complexity of geological conditions and the occlusion of 3D streamlines reduce the readability of the streamline charts. After discussing the constructing process of streamlines, we narrow down the problem to placement of initial particles. Considering the geological properties of groundwater flow and the local placement method, we propose the principle for global placement, which was checked based on the hydrogeological conditions of Yingjun No. 1 Mine of Shanghaimiao mining area in Etuokeqian Banner, Inner Mongolia. The obtained streamline charts clearly represent the groundwater flow and uncover the control action of a window. The results demonstrate the rationality and validity of the global principle and provide visual and scientific data for mine water research and management decision.
