摘　　要：DTM法土方量计算是工程施工中较为常用的一种方法,选取不同的高程点将获得不同的DTM,进而会影响到工区内土方量计算的精度。本文对不同工区的多种高程点选取方式进行了实验及分析,从中总结了一种较为有效的并兼顾精度的工区边缘高程点选取方法。Earthwork calculation based on DTM is a commonly used method in the constructions .Different selections of elevation points which bring different DTMs affect the calculation of earthwork in precision .In this paper , some methods of elevation points se-lections about different workareas were discussed , a more effective and accurate methods of elevation points selections was developed .
