| 摘 要： | 传统的方格网法测量土方量工作量大,精度无法评估;而三角网法测量土方量虽然精度高,但可读性差,客户不愿采用。针对这种情况,作者采用方格网与三角网相结合的方法测量土方量,既提高了土方测量的效率,又保证了土方计算成果的正确性,很好地解决了这一难题。

| Abstract: | The traditional grid network for the measurement of earthwork workload,accuracy cannot be assessed;and the trilateration network earthwork although measurement of high precision,but poor readability,customers want to adopt.In view of this situation,the author adopts the grid and triangular mesh combination method for the measurement of volume of earthwork,which not only improves the earthwork measurement efficiency,and ensure that the earthwork calculation results are correct,compeletly solution to this problem. |
