摘要: 由于露天矿地形复杂、剥离后的采矿工程复杂,利用方格网法计算土方量误差较大。利用三角网(TIN)建立DTM模型计算土方量精度高,这种方法可以重现剥离土方量的形态特征,与实际工程体形状最接近,计算土方量方法最优。

Abstract: Due to the complexity of the original terrain and open-pit mining engineering terrain, grid method using in earthwork calculating has larger measurement error. The establishment of DTM with TIN model using in earthwork calculating has high-precision. The method can reproduce the form of earthwork, be closer to the actual shape of the earthwork, and be optimal.
