| 摘 要： | 结合某黄河公路大桥建设中的高程控制测量,论述了无仪器高跨河水准测量的原理、设计方法、测量程序、精度分析等问题,并依据跨河水准测量的特点,重新推导了在跨河水准网中测距三角高程的精度估算公式,消除了仪器的量高误差.最后针对跨河水准网进行严密平差处理,并与估算的结果进行了比较.

| Abstract: | The paper introduces the theory, design proposal, method, precision analysis of river-crossing leveling, which was executed in vertical control surveying of Huanghe river road bridge in Luoyang. Besides, the article gives out new precision estimation formula of trigonometric leveling with distant measure in river-crossing leveling and calculating result with author's adjustment program in VB 6.0. At last, some important conclusion was arrived by comparing estimation with adjustment result. |
