Oceanic Tide Loading Correction of the Water Level Tide M_2 Wave of the Pressure Wells

Cao Jing-quan

Abstract

Applying the Schwiderski model of global ocean tides and the method of Green function integral,we conduct the harmonic analysis and residual calculation of the water-level-tide M2 wave observed by seven pressure wells in Beijing,Tianjin and Tangshan.The result shows that the standard deviation of tide factor shifts from 2.263 to 0.898 and the standard deviation of phase shifts from 4.57° to 3.58° after the oceanic tide loading correction.
