| 摘 要： | 通过对方格网法在大比例尺地形图上计算挖（填）土石言精度的讨论，澄清了方格网边长与土石方量计算精度的关系，当土石方量计算精度一定时，对于不同的场平面积、地形图比例尺、地形坡度、施工高度，应采用不同的方格边长，一般情况下，不宜在１：２０００或更小比例尺图上进行，方格网边长不宜小于１ｍ。

| Abstract: | This paper discusses the accuracy of calculating cuts and fills Earthwork with the method of square grid in large scale topographic map.and clears up the relationship of the side longth of square grid and the accuracy of Earthwork calculation.In the result,when the cudculation accuracy don't change,the different side longth ought to be carried,in the condition of different area,scale,slope and elcvation.And,generally,the topographic map scale is more thurt 1 0 2000,and the side lougth is more than I meter in best. |

| Keywords: | the side longth of squre grid Earthwork erea topographic scale |
