Combined with the digital elevation model characteristics, this paper improves the grid method that is used to calculate earth-rock volume.
结合数字高程模型的特点，对土石方工程量格网法计算方法进行改进。
This method can be used not only in the quantity calculation of the earth-rock work, but also in the calculation of analogous volume and capacitance.
该方法不仅适用于土石方量的计算，也适用于与此类似的工程体积、容量计算。
