| 摘 要： | 通过对三角高程测量高差公式的推导,对其高差中误差进行了系统的分析,可知高差中误差主要取决于测距误差和测角误差,根据成绵乐客专桥墩高程控制测量和牛兰江—滇池补水工程高程控制网复测及加密实例分析,可知三角高程测量方法在一定条件下可以替代常规水准测量,精度满足四等水准测量要求。

| Abstract: | This paper systematically analyzed the height mean square error, and the height mean square error mainly depended on ranging error and angle measurement error. According to the following instances ： the bridge pier height control of the Chengdu - Mian-yang - Leshan passenger dedicated railway line, the repetition surveying and control extension of height control network in Niu - Lan - Jiang to Dian - Chi replenishment project, they all proved that trigonometric height measurement can replace leveling measurement in certain conditions, the precision can reach the requirements of four - grade - leveling measurement. |
