摘要
近年来,建筑信息模型(BIM)技术在岩土勘察行业慢慢推广应用,而岩土勘察作为工程项目全生命周期中的重要环节,对于建立准确直观的三维地质模型是必不可少的.结合实际工程项目,对地质勘察的钻孔数据进行三维可视化,然后在此基础上,利用遗传-克里金插值算法,以钻孔数据为样本插值出三维地质层数据.根据三维地质层数据,在Revit软件中实现由钻孔到地质层面,再到地质体的三维地质模型建模.结果验证了遗传-克里金插值在三维地质建模方面的有效性,实现了地层模型的可视化,可以更加清楚各地层及地下构建物的分布.
Recently,BIM technology has been gradually promoted and applied in the geotechnical survey industry.As an important part in the engineering project life cycle,geotechnical survey is essential to establish an accurate and intuitive three-dimensional geological model.Based on the actual engineering project,the borehole data of geological survey are firstly visualized in three-dimensional in this paper,then the genetic-Kriging interpolation algorithm is adopted to fit the three-dimensional geological layer data based on the borehole data.Finally,according to the three-dimensional geological layer data,the three-dimensional geological model is constructed from borehole to geological level,then to geological body in Revit software.The results verify the validity of genetic-Kriging interpolation in 3D geological modeling,realize the visualization of stratigraphic model,and make the distribution of strata and underground structures clearer.
