摘要
本文对水准测量中关于地球潮汐改正的几个问题进行了探讨。给出了潮汐改正计算的实用公式。并利用从北京至厦门3463公里的精密水准测量资料和沿线地倾斜台站的实测潮汐因子γ值,试算了潮汐改正值。从理论上论证了潮汐改正的量级最大为0.1毫米/公里和南北向水准测线的改正数较大而东西向很小的结论。
In this paper, some issues referred to the earth tide correct in leveling are discussed, and a practical formulas of tide correction is given. Test calculation is also performed, using the precise leveling data got in the line from Beijing to Xiamen , about 3463 kilometers long, and the data of tide factor γ value got in the solid tide station along this line. A conclusion is proofed theoretically that maximum tide correct value is 0.1 mm/km, and the correct value along the line in the North-South dirrection is greater than that in the East-West dirrection.
