【摘要】 计算机技术在勘察领域的应用越来越广泛,近年来随着信息技术特别是计算机图形学、地理信息科学、三维岩土工程建模和三维工程分析技术的发展,兴起的三维岩土工程勘察信息技术,更是受到业界人士的广泛关注。它能够对各种原始数据、图像、图件、文字报告进行综合动态管理,并在此基础上生成二维地质剖面图、三维地质模型等,提高了数据可视化程度,直观形象地表达了构筑物及区域地质单元的空间展布规律,实现工程智能决策,以充分挖掘工程信息的价值。本系统首次实现利用导入钻孔进行三维建模并且手动调整尖灭比例设置;利用层面的下沉方式对地层进行解译,解译过程支持人机交互控制层面,通过对建模参数设置控制模型的精度、范围及插值效果,最终自动生成地质体,实现三维分析应用,实现三维数据与剖面图转CAD图。更多还原

【Abstract】 Computer technology is more and more widely applied in the field of exploration, in recent years, along with the information technology, computer graphics, geographic information science, in particular the threedimensional geotechnical engineering modeling and the development of three-dimensional engineering analysis technology, the rise of 3 d geotechnical engineering information technology, but also received extensive attention of the industry. It can be for a variety of original data, images, maps, text, the report makes a comprehensive dynamic management on the basis of generating 2 d geological profile, 3 d geological model, improved the degree of data visualization, intuitive image to express the structure and the spatial distribution regularity of regional geological unit, realize the intelligent decision, to fully tap the value of engineering information.This system for the first time use import drilling for 3 d modeling and manual adjustment, pointed out the proportion set;Level of sinking method is used to analyse the formation interpretation, interpretation process support the human-computer interaction control level, through the modeling parameters setting control precision and range of the model and the interpolation effect, automatic generation of geological body, eventually realize the three-dimensional analysis application, realizes the 3 d data and profile of CAD drawing.更多还原
