摘要
用数学方法识别与处理了厦门台地倾斜资料,提出了两种海潮对厦门台地倾斜干扰的可能机制。从处理结果可以认为:由于特殊的地理环境,地倾斜南北分量受到的干扰主要来自于海潮幅度,其表现形式为观测幅度增大;而地倾斜东西分量受到的干扰则来自于海潮幅度与海流两方面,海流的干扰造成了观测曲线中的"双峰"现象。
Having processed and discriminated the ground tilt data of Xiamen seismostation with mathematics methods, two kinds of possible mechanism of sea tide disturbing ground tilt at Xiamen seismostation are presented. It is shown that as a result from the special geographical environment, the disturbance on NS component comes from the sea tide magnitude mainly, its manifestation is increment of the observation magnitude, while the disturbance on EW component comes from two aspects sea tide magnitude and ocean current, the disturbance of ocean current makes "double peaks" on observation curves.
