| 摘 要： | 根据加卸载响应比理论，利用１９９０～１９９７年新疆０４井水位动态观测资料，分析了井水位对地球固体潮汐的响应。通过彼尔采夫滤波、气压和水位相关分析，剔除水位长趋势变化和气压的影响，计算出井水位固体潮体应变的响应率，合理地选取加载和卸载的时段，得出水位固体潮加卸载响应比，其值为１左右。水位固体潮加卸载响应比变化特征为年变平稳、幅度小，在中强地震活动时出现比值短期增高现象，异常大多出现在震前１～３个月内

| Abstract: | The response of water level in Xinjiang Well 04 to solid tide is analyzed by means of loading/unloading response ratio theory.The process is:first,removing the effect of long time trend variation of water level and the effect of air pressure by Bertsev's filtering method and relative analysis of air pressure and water level,and calculating the response rate of solid tide body strain of well water level;then,reasonably choosing loading and unloading time interval,working out loading/unloading response ratio of sold tide of water level.In this paper,the value is gotten to be about 1.It is thought that the loading/unloading response ratio of solid tide of water level in well 04 has follwing Characteristics:annual variation is steady and the amplitude is small;a short time increase in the ratio appears 1~3 months before most moderate earthquakes. |
