摘要
对工程土石方量计算中的等高线法、断面法、方格网法以及基于数字高程模型(DEM)法的基本原理、方法和优缺点进行比较分析,从理论上讨论它们的实用范围、测量条件并进行精度分析,进而找出存在问题并给出结论。
In this paper, the calculation of earthwork in the contour method, section method, square control network method and the digital elevation model （DEM） are compared and analyzed about the basic principles, methods, advantages and disadvantages. Their practical range and measurement conditions are discussed and analyzed, then the existing prob- lems are found out and the conclusion was given.
