摘要

本文收集了2008—2018年3号井数字化水位观测对地震同震响应的数据资料,分析了井水位对7.8级以上大震的响应能力和同震变化特征。结果显示,3号井对远场大震响应能力较强;水位同震响应类型均表现为阶降;水位同震响应变化幅度与震中距和震级有明显的关联性;从同震响应方向来看,远场大震对本区域构造应力的影响以张应力为主。
        This paper collected the data of the digital water level observation of the No. 3 well from 2008 to 2018 on the earthquake coseismic response, and analyzed the response capacity and coseismic variation characteristics of the well water level to large earthquakes above 7.8. The results show that No. 3 well has strong response to far-field large earthquakes; the water level coseismic response type shows a step-down; the magnitude of the water level coseismic response has obvious correlation with the epicenter distance and magnitude; from the perspective of coseismic response, the influence of far-field large earthquakes on tectonic stress in this region is dominated by tensile stress.
