摘　　要：就土方工程量的计算,目前主要有方格网法、等高线法、平均断面法、DTM法等。文章首先从理论上对各方法的计算精确性进行了探讨,通过实例说明,采用三角棱柱体法可以得出精确值,而采用四方棱柱体法则不一定能得出精确值,即使天然地面方格的各角点共平面;再在实际操作层面,对各方法的适用范围进行了探究;指出相较于其它几种方法,基于三角棱柱体体积计算方法的DTM法,其精确性相对更高、适用范围更广。Regarding the calculation of earthwork quantities,there are currently mainly grid method,contour method,average section method,DTM method,etc.The article first explores the computational accuracy of each method from a theoretical perspective.Through examples,it is demonstrated that using the triangular prism method can obtain accurate values,while using the square prism method may not necessarily result in accurate values,even if the corners of the natural ground grid are coplanar.At the practical operational level,the scope of application of each method was explored.Compared to other methods,the DTM method based on triangular prism volume calculation has relatively higher accuracy and wider applicability.
