摘　　要：为了提升水电站道路设计水平,文章总结了DEM模型的数据采集和建模方法,并基于规则格网、不规则三角网分别建立道路土石方计算模型。同时,以某水电站进场道路为研究对象,将基于DEM模型计算的土石方工程量与平均断面法进行对比,研究成果表明,DEM模型能更好地拟合地形和道路线形,计算的土石方数量更准确。In order to improve the design level of the hydropower station roads,the data acquisition and modeling methods of the DEM model are summarized,and the road earthwork calculation model is established based on the regular grid and the Triangulated Irregular Network.At the same time,taking the access road of a hydropower station as the research object,the earthwork quantity calculated based on DEM model is compared with the average cross section method.The research results show that the DEM model can better fit the terrain and road alignment,and the calculated earthwork quantity is more accurate.
