本文根据我国丹东、佘山、泉州,蒲田、厦门,漳州六个沿海台站的地倾斜观测资料,按维尼迪科夫法对资料进行了调和分析;得出了海潮对固体潮水平分量影响的规律和特点,并指出我国沿海台站负载潮的相位滞后固体潮十余小时。 由于负载潮受局部因素影响较大,本文提出用台站附近验潮站的水位资料或验潮站的海潮予报值进行相关分析来排除海潮的影响是行之有效的。其余差与固体潮理论值有很好的一致性。这将有助于提高我国沿海台站形变资料的分析精度和捕捉地震前兆信息的能力。
Based on the data of ground tilt of six coastal stations in Dandong, Sheshan, Quanzhou, Kamata, Xiamen and Zhangzhou in our country, the data were reconciled according to the method of Wididiskoff; the law of the influence of the tide on the horizontal component of solid tide It also points out that the lag behind the tide of load in China’s coastal stations is more than ten hours. As the load tide is greatly affected by the local factors, this paper proposes that it is effective to exclude the influence of the tide by correlating the water level data of the tide gauge station near the station or the tide gauge value of the tide gauge station. The remaining difference is very consistent with the theoretical value of solid tide. This will help to improve the analysis accuracy of deformation data of coastal stations in China and capture the information of earthquake precursors.
