The observation of gravity solid tide at Dalian station has been greatly affected by ocean tide load. In this paper,based on the selected ocean tide models,we select gravity data for preprocessing to obtain gravity tide parameters,to carry out ocean tide load correction and evaluation analysis on O₁,K₁,and M₂ waves. The numerical analysis shows that the eight global ocean tide models have little difference in the effectiveness of the load correction of the main tidal waves. The gravitational ocean tide load amplitude distribution frequency bands of the O₁,K₁ and M₂ waves are between 2.4 and 2.8μGal. The residual load correction effectiveness of the three main tide waves is 43％～53％,and the eight ocean tide models have relatively small differences in the correction of the main tide waves of Dalian station.
