在钻孔数据较少时,为提高小比例尺三维地质模型的精度,利用GMS软件根据多层DEM建立模型。该文通过分析实际条件下地层分布特点,提出了不同数据精度下DEM相交计算的原则。将修改后的DEM导入原模型中,再次插值形成三维地质模型。利用GMS软件得到的三维地质模型,具有可查询,可任意角度任意位置切割剖面的功能。

On the premise of less borehole data, in order to improve the accuracy of small scale 3D geological mod?el, multi layer DEM model using GMS should be established. In this paper, through analysing distribution charac?teristics of layers under actual condition, the principle of DEM intersection calculation under different data accuracy have been put forward. After modifying the original DEM, importing them into the original model, and interpolating again, 3D geological model has been formed. 3D geological model has the function of cutting section at any position and at any arbitrary angle. Its higher accuracy lay a good foundation for the next step of hydrology simulation.
