摘　　要：针对目前广泛使用的道路土方量计算方法不够准确的缺点,以数字地面模型的重构为技术核心,给出了土方量的三维计算方法。结合工程实例,将三维计算方法的结果和传统方法的结果进行比较,结果表明该方法计算准确、可行。Because the current calculation method of roadway earthwork volume is approximate with its theoretical defect, with digital terrain model (DTM) and its re-triangulation techniques, this paper presented a 3-D algorithm of calculating roadway earthwork volume. It is pointed that the method leads a true value in theory, and ensures a higher accuracy compared with the traditional method in practical tests. This result indicates that the method is feasible.
