摘　　要：针对传统三角高程测量相对水准测量精度较低的问题,本文将新三角高程测量方法作为研究重点,从三角高程测量原理出发,根据误差传播率,推导出了计算传统三角高程测量和新三角高程测量高差精度的数学模型。实验对比分析了新三角高程测量与水准测量、传统三角高程测量的精度情况,结果表明新三角高程测量方法简便灵活,省时省力,能提高作业效率,同时达到了三等水准测量精度要求,具有广泛适用性。In view of the low accuracy of relative level measurement of traditional triangular elevation measurement,this paper takes the new triangular elevation measurement method as the research focus,starting from the principle of triangular elevation measurement,and according to the error propagation rate,derives the mathematical model of calculating the accuracy of the elevation measurement of the traditional triangular elevation and the new triangular elevation measurement.The experimental analysis of the accuracy of the new triangular elevation measurement and the traditional triangular elevation measurement shows that the new triangular elevation measurement method is simple and flexible,saves time and effort,can improve the working efficiency,and meets the requirements of third-class measurement accuracy at the same time,which has wide applicability.
