摘要
结合连云港西大堤平面位移监测实际 ,用统计检验方法对视准线观测的位移反向问题进行了较为深入的研究 ,得出了海堤上视准线观测受堤顶折光影响显著的结论。在大型海工建筑物的精密测量中有必要考虑大气折光影响。
On the basis of the monitoring practice for the west dam in Lianyungang, this paper discusses the effect of atmospheric refraction on the displacement measured by collimation line method. It concludes that this effect should be concerned in precision marine survey.
