【摘要】 选取福建安溪一号井,利用阶变响应幅度与震级、震中距之间的定量关系,分析该井的同震阶变响应特征。研究表明,降雨对井水位的同震阶变响应有一定影响;降雨通过载荷作用改变井口附近的局部应力状态,从而影响井水位对地震的响应能力。更多还原

【Abstract】 By using the quantitative relationship between the well water level change and the earthquake magnitude,the epicentral distance,this paper statistically investigated co-seismic water level step characteristics of Anxi-1 well,Fujian Province.It means that the rainfall loading, which might change the local tectonic stress state within the well area,can make an influence on co-seismic water level changes.更多还原
