摘要:
地震会造成震源周围地质结构的应力状态变化，导致含水层的受力状态相应改变，因而深井的水位也会出现同步变化。本文针对山东省邹城市的特殊地质结构，以该市岳庄深井所记录的水位监测数据统计结果为基础，进行了地震同震响应特征分析。结果表明，该深井的水位变化对ML 4.0震级以上地震呈现良好的同震响应特征；记录的地震同震响应特征可分为五种类型，其中阶梯型和振荡型出现频次较高，是主要的两种类型。因此，利用该深井的水位监测统计数据进行地震的同震响应特征分析和开展地震监测是一种可行的方法。
The earthquake can change stress state around geological structure so as to cause stress change in the aquifer layer and a synchronous change of the deep well water level. This paper dealt with the seismic response characteristic based on the special geological structure of Zoucheng City in Shandong Province and the water level monitoring statistical data of the Yue Zhuang deep well. The research results showed that this deep well had a good response ability to the seismic above ML4.0 level. The recorded coseismic response characteristics can be divided into five kinds in which the ladder and the wave modes are occurred in higher frequency. Therefore the water level monitoring statistical data and seismic response characteristic of the deep well can be used to provide a good way for earthquake monitoring.
