With the tidal data from the stations of Langjishan, Diaobang and Xiadachendao, and 7 strips vertical observed data of spring tide and moderate tide, the characteristics of the tide and tidal current near Huangjiao work zone were analyzed. The results show that the tide is regular semidiurnal while the tidal current is nonregular semidiurnal. The tidal current at 1-5# vertical tidal observation stations are rectilinear while 6# and 7# are rotated. The tidal waves in the sea area near the Taizhou Bay are standing waves.
