从固体潮改正公式出发,分析了应用该公式存在的时间、距离和方位不确定等问题,结合精密水准测量作业实际,提出了基于测站的固体潮改正方案,并以连云港地区布设的两条微型水准路线为例,比较了按测段和测站改正固体潮影响的效果,结果显示按测站改正固体潮结果更精确。
In this paper,having studied the correction formula of the solid earth's tides given by the national norms,we find that the formula has the problems of uncertainty of time,distance,direction and so on. Then,from the point of view of precision leveling,a solid earth tides correction scheme based on station is put forward,we laid out two micro level routes in Lianyungang. According to the study of data obtained from the both routes,we compared the effect of the solid earth tides on the measurement section and the station. The result shows that the influence of the station correction tide is more accurate.
