摘要: 土方量计算直接关系到工程施工的费用概算及方案选优,是工程施工阶段的一个重要环节。采用方格网法计算土方的三种情形公式,结合实际算例分别进行详细比较与分析,得出三种情形公式均满足填挖平衡设计原则,并在实践中广泛应用。当进行地形起伏无规律的场地平整时,选取不同的方格网法计算土方公式,结果会有较大差异。建议通过加密高程点和缩小方格网边长来提高计算精度,土方计算可借助主流测绘软件CASS系统来轻松实现。

Abstract: The earthwork calculation is directly related to the cost estimate and the selection of the project,and it is an important link in the construction stage.  Three cases formula about the grid method of earthwork calculation is adopted in this paper,and the comparison and analysis are carried out in detail by means of the practical example.  Three cases formula meets the design principle of cut and fills balance and have been widely applied.  When the terrain without regular ground leveling,the results may he different if the formulas for calculation of earthwork grid method are different.  Suggestions to improve the precision are put forward by increasing elevation points and reducing the grid length,the earthwork calculation is easily achieved with the help of the main mapping software CASS.

Key words: grid method, earthwork calculation, cut and fill balance, field leveling, CASS software
