1、 摘要摘要 用水准测量方法测定地面点的高程，由于其精度高，普遍用于建立高 程控制网。但是对于地面高低起伏较大或不便于作水准测量的地区，用水 准测量方法进行高程测量则进度缓慢，甚至不容易做到。在这种情况下， 常采用三角高程测量方法测定高程。随着高精度测距仪的普及应用，用三 角高程测量代替水准测量建立高程控制网，可以大大加快野外测量的速度。 本文将在分析三角高程测量误差来源及测量精度的基础上，提出用全 站仪中间法进行三角高程测量的方法，推导出了全站仪中间法高程测量的 计算公式，并运用误差传播定律导出了高程测量精度计算公式，分析了有 关误差对高程测量精度的影响。特别是在地形复杂的困难条件下，对用全
