| 摘 要： | 工程施工前的设计阶段必须对土石方量进行预算，它直接关系到工程的费用概算及方案选优。在现实中的一些工程项目中，因土方量计算的精确性而产生的纠纷也是经常遇到的。如何利用测量单位现场测出的地形数据或原有的数字地形数据快速准确地计算出土方量就成了人们日益关心的问题，比较经常使用的几种计算土方量的方法有：方格网法、断面法、平均高程法和DTM法（不规则三角网法）等。

| Abstract: | The budget of earthwork before construction engineering design is related with project cost estimates and program optimal selection directly. In some practical projects, many disputes by of the accuracy of earthwork calculation have been encountered regularly. How to use the terrain data by field measurement or original digital to calculate earthwork fatly and accurately has been growing concern. Some methods of earthwork is： grid method, section method, average elevation,and DTM. |
