工程土石方量计算方法的对比研究

Comparative Study of Earthwork Calculation Method

为了工程建设、施工中的土石方计算更为准确,控制工程的费用,本文采用比较研究方法对DTM法(不规则格网法)、断面法、方格网法和等高线法等进行了分析研究,讨论其原理、精度和适应性,并用实例进行证明。研究表明,因地制宜,综合权衡精度、速度、成本对土石方量计算方法进行抉择,才能达到方案最优。

In order to enhance the project construction earthwork calculated more accurately, DTM （irregular grid method）, section method, grid method and contour method are studied with Comparative Study. Their adaptability and accuracy are analyzed; and their principle, precision and adaptability are discussed. The case study has shown that tradeoff local conditions, accuracy, speed and cost of earthwork computation method are the optimal program.
