Based on the 3D strata modeling method of multi-layer DEM,the general workflow of building the 3D visualized strata model with bore-hole data generating TIN model of different stratum surface in ArcGIS is summarized. The modeling instance shows that this method is a simple and effective way to obtain the 3D strata visualized model,and could offer reference for similar engineering.%基于多层DEM地层建模思路，总结了在ArcGIS中利用钻孔数据生成地层分界面TIN模型来实现三维地层建模及可视化的一般方法，建模实例表明，该方法简单、高效，可以快速建立层状地质体的三维可视化模型，可以为类似的工程提供参考。
