Automatic hydrogeological profile drawing method cconsidering water abundance partition

研究顾及富水性分区的水文地质剖面图的自动绘制方法,可以直观形象展示地下岩层的结构和地下水运移条件.基于浏览器/服务器(B/S)的架构模式,耦合含水层富水性分区条件与地层结构信息,构建了水文地质剖面数据模型,讨论了剖面线与富水性分区多边形的空间关系.分别从前端数据获取、地层信息处理、剖面图整体框架生成、含水层与隔水层绘制、富水性分区构建等5个方面阐明了水文地质剖面图的自动生成步骤.以江苏南通市实际水文地质钻孔资料为例,对任一剖面线的水文地质剖面图进行自动绘制和可视化,增强水文地质地层信息的直观性,减少水文地质剖面的解译难点.顾及富水性分区的水文地质剖面图的自动绘制能够为综合考虑区域的水文地质条件、有效指导地下水资源合理开发提供空间辅助决策依据,具有较高的应用推广价值.

This paper studies the automatic drawing method of hydrogeological section considering water abundance partition,which can visually display the underground rock structure and groundwater migration conditions.Based on the"Browsers and Servers"architecture mode,the hydrogeological profile data model is constructed by coupling the aquifer water abundance partition conditions and stratigraphic structure information.The spatial relationship between section lines and water abundance partition polygons is discussed.Moreover,the automatic generation steps of hydrogeological profile are illustrated from the following five aspects:Web front-end data acquisition,stratum information processing,profile overall framework generation,aquifer and aquifuge drawing,and water abundance partition construction.Taking the actual hydrogeological data of Nantong City,Jiangsu Province as an example,realizing the automatic generation and visualization of any path geological profile.In addition,the visualization of hydrogeological underground space is enhanced,and the difficulty of geological profile interpretation is reduced.The automatic drawing of hydrogeological profile can provide the basis for analyzing the regional or local geological conditions systematically,guiding the development and utilization of underground resources and the implementation and construction of the project correctly,so it has high application and popularization value.
