中卫倪滩井数字化水位同震响应特征分析
|
Abstract:
本文选取了2008年~2020年中卫倪滩水位对大陆7级以上地震的同震响应资料，统计了水位同震响应的形态特征、记震能力、变化幅度等。结果表明，水位对大陆7级以上地震的记震能力较强，同震变化主要为震荡型，响应时间较短，震荡后，水位曲线仍然按照原来正常形态变化。水位变化幅度与震级和震中距相关性不明显。
In this paper, the co-seismic response data of water level in Zhongwei Nitan to earthquakes of M ≥ 7 in mainland China from 2008 to 2020 are selected, and the morphological characteristics, seismic recording ability and variation range of water level co-seismic response are counted. The results show that the water level has a strong ability to record earthquakes with M ≥ 7 in the mainland. The co-seismic changes are mainly concussion type and the response time is short. After concussion, the water level curve still changes in accordance with the original normal form. There is no obvious correlation between water level variation and earthquake magnitude and epicenter distance.
