摘　　要：整理了聊古一井水位2000-2012年所记录到的同震效应,并对3个不同阶段内的同震效应进行了特征分析。结果表明：聊古一井的同震效应为振荡型和振荡阶升型;该井对来自环太平洋地震带的地震记录能力较强;该井水震波记录随震级增大而增加、随井震距的增大而缩小的特征并不明显。该井对全球8级以上地震有很好的记录能力。激发自流以及变频稳流状态下,聊古一井水位记震能力有所下降。The characteristics of coseismic effects in three stages of Liaogu- 1 well in 2000 - 2012 are analyzed,and the results show that the coseismic effect of Liaogu- 1 well can be divided to oscillation type and oscillation step-up type. The seismic recording capability of liaogu- 1 well is very strong to earthquakes in the circum Pacific seismic belt. The ascending of descending amplitude of groundwater level in a single well usually increases with growing magnitudes of earthquakes and decreases with increasing well-earthquake distances,but this characteristic in Liaogu- 1 well is not obvious. The well has a good ability to record for M ≥8. 0earthquakes in the global. Liaogu- 1 well water level recording capacity declined in the artifical self-flow observation and frequency conversion of submersible pump obversation.
