摘要
从三角高程测量的原理出发,推导了利用对向三角高程测量计算大气折光系数的公式,并利用跨江三角高程测量的大量实测数据,计算分析了某大桥跨江高程传递区域大气折光系数的变化规律,得出一些有意义的结论。
The atmospheric refraction coefficient formula is derived using the principle of trigonometric leveling survey. With massive measured data of the river-crossing trigonometric leveling survey, the change rule of atmospheric refraction coefficient is calculated and analyzed in elevation transmission region of a bridge, and some beneficial conclusions are obtained.
