文中针对导航及地理信息系统的迅速发展,传统的二维岩土工程勘察图纸已不能够为计算机信息处理提供大量、简捷和直观的岩土勘察信息的问题,提出了三维建模技术和可视化技术.该技术在分析和测量大量的勘察资料的基础上,运用三维立体建模和可视化编程软件技术,实现了岩土勘察地形的立体空间模型,并在可视化技术下,该场景真实逼真,该模型的提出为岩土勘察工程提供了重要的参考价值,且在未来的发展中有较强的实用价值.%This paper for navigation and geographic information system (GIS) the rapid development, the traditional 2D geotechnical engineering survey drawings have not been able to provide a large number of computer information processing, simple and intuitive geotechnical investigation information problems proposed 3D modeling technology and real-time visualization technology. The technology on the basis of analysis and measurement of a large amount of investigation data, using 3D solid modeling and visualization programming software technology, can realize the geotechnical survey the terrain of three-dimensional space model, and in the visualization technology and the real scene realistic, the model proposed for the geotechnical engineering investigation provides important reference value, in the future development has a strong practical value.
