| 摘 要： | 摘要已知点的分布密度直接关系到高程的拟合精度。文章以待求点与已知点间隔约500m、1000m的线路利用不同模型来拟舍线路进行精度分析，通过运用不同几何模型、不同的分布密度拟舍长线路高程得出了一些有益结论，为工程前期设计提供一些参考资料。 |

| Abstract: | The known point distribution density is directly related to the elevation fitting precision.The paper analysis the precision of the known point and stay point for intervals of 500meters,1000meters to the fitting line,by using the different geometric model different distribution density fitting long-line elevation to draw some useful conclusions,and to provide some reference for preliminary engineering design. |
