摘要
土方量计算的精度不仅影响平整后的土地质量,还影响到土地平整工程的投资与效益问题。针对3种不同坡度范围的测区,分别用DTM法、方格网法、散点法以及区域平衡法等计算出土方量,并进行横向和纵向对比分析,得出不同方法的适宜坡度范围和精度。
Earthwork calculating not only has impact on land quality after flatting project, but also the problem of investment and benefit of land. In the paper, based on DTM method,square grid method,disperse point method and area balance method, we calculated earthwork on 3 kinds of terrain slope. After the contrastive analysis on landscape and portrait, we could know the appropriate slope and accuracy of different methods.
