研究了地质钻孔信息的管理和可视化技术,提出了一种在数字地球平台中进行城市钻孔信息模拟和可视化的方法。该方法基于一个统一的钻孔数据库标准,首先将钻探点位信息和地层分层信息组织成具有不同细节层次的钻探点位模型、钻孔分层散点模型和钻孔管段模型,然后构建基于细节层次模型的海量钻孔信息多尺度表达机制,最后将这些模型加载到数字地球平台中进行可视化及查询、分析。在上海市的应用实例显示,该方法实现过程简单、自动性高,生成的模型易于在国际互联网上进行分发、集成与共享。该方法的应用将有助于地质工作者向其他科技人员以及社会公众展示、分发自己拥有的钻孔信息,为以钻孔数据为代表的城市地质信息的社会化服务奠定基础。
Studied the management and visualization technology of geological drilling information and put forward a method to simulate and visualize urban drilling information in digital earth platform. Based on a unified drilling database standard, the method first organizes drilling site information and formation stratification information into drilling site models with different levels of detail, drilling layered scatter model and drilling pipe section model, Level model of multi-scale mass drilling information expression mechanism, and finally these models are loaded into the digital earth platform for visualization and query, analysis. The application example in Shanghai shows that this method is easy to implement and highly automated. The generated model is easy to distribute, integrate and share on the Internet. The application of this method will help geologists to show and distribute their own drilling information to other scientific and technical personnel as well as to the general public and lay the foundation for the socialization of urban geological information represented by borehole data.
