摘　　要：土石方是工程建设中一项基础性的工作,并且是工程造价中重要部分之一。为提高土石方计算精度,以及后续工程款拨付的依据,对数字地面模型(DTM)法、断面法和方格网法,根据大型土石方实测数据,使用3种方法分别对2地块进行计算土石方工程量。结果表明:DTM法计算土石方量在不规则地形条件下大型土石方外运中比较适合。Earthwork is a fundamental task in engineering construction and an important part of project cost.In order to improve the accuracy of earthwork calculation and provide a basis for subsequent engineering payment,based on large-scale earthwork measurement data,this paper uses three methods:digital terrain model(DTM)method,cross section method,and grid method to calculate the earthwork quantity for two plots.The results indicate that DTM method is more suitable for calculating the volume of earthwork in large-scale earthwork transportation under irregular terrain conditions.

关 键 词：DTM法 方格网法 断面法
