摘要
参照《国家一、二等水准测量规范》,在二等跨河水准的测量(测距三角高程法)中,采用两台全站仪同时对向观测,大大削弱了大气折光的影响,简化了作业过程,提高了作业效率。为保证测量精度,对每次对向观测的测量精度进行了分析。
The precise trigonometric leveling is used for river-crossing leveling and the details of the method are based on the specification for the first and second order leveling. Simultaneous reciprocal observation is realized by setting the two total stations at each side of the river. The influence of atmospheric refraction is decreased and the workflow is also simplified and more efficient. The accuracy of reciprocal observations is analyzed at each time to guarantee the accuracy of the final results.
