本文用最大熵功率谱法对水井水位、理论固体潮、气压、海潮等观测数据求蕴涵客观周期,由最小二乘解求振幅、相位谱,得到由振幅比和相位差求井孔影响系数与滞后时间的方法。由于气压资料中没有类 M_2波,利用 M_2波振幅比研究24口井孔的反映能力,得出与 Melchior“M_2波振幅随含水层埋深而增加”的不同结论。对天然水震波和井中人工爆破试验的数据进行最大熵谱分析,得出反映水震波是由于在周期15—50秒范围内井孔放大特性较好所致。
In this paper, the maximum entropy power spectrum method is used to calculate the objective period of well water level, theoretical solid tide, barometric pressure and ocean tide. The least square solution is used to find the amplitude and phase spectrum. Lag time method. Since there are no M_2-like waves in the barometric data, we use the amplitude ratio of M_2 wave to study the response of 24 wells, and draw different conclusions with Melchior’s “M_2 wave amplitude increases with the depth of the aquifer”. The maximum entropy spectrum analysis of the natural water shock waves and the artificial blasting data in the wells shows that the reflection of the water shock waves is due to the better wellbore amplification characteristics in the period of 15-50 seconds.
