基于压力式验潮仪的潮汐应急观测可行性研究

Research on the Feasibility of Emergency Tidal Observation Based on Pressure Tide Gauges

针对沿岸验潮站点布局密度不够的问题,使用压力式验潮仪对遮浪站附近海域进行潮汐应急观测,对实验数据进行了回归分析处理,并计算了实验数据的误差和相关系数。结果表明,台风灾害过程中,压力式验潮仪具有良好的稳定性,压力式验潮仪潮位与实际潮位的数据曲线基本吻合,两者的相关系数均在0.99以上;此外,压力式验潮仪潮位误差绝对值均小于5 cm,反应了压力式验潮仪潮位数据能较好地反应台风灾害过程中实际潮位的变化,表明使用压力式验潮仪开展潮汐观测工作具备良好的可行性。

In order to solve less distribiton of tide gauges along coast,pressure tide gauge is used for tidal emergency observation of the sea area near zhelang station.the experimental data were processed by regression analysis,We also calculate the error and correlation coefficient of experimental data.The results show that the pressure tide gauge has good stability during the typhoon.And the tidal level data curve of the pressure tide gauge was basically the same as the measured tidal level data curve.The correlation coefficient between the tidal level data of the pressure tide gauge and the measured tidal level data is 0.99.Besides,the absolute value of the tidal level error is less than 5cm,it reflects that the tidal level data of the pressure tide gauge can well reflect the change of measured tidal level during the typhoon.Thus it is indicated that the tidal emergency observation working of the pressure tide gauge has high feasibility.
