摘要
以地下水作为加卸载动力,对每年地下水位上升与下降期间,金州台水准高差的响应情况进行对比分析研究。结果表明:当地下水位在覆盖层内变化时,水准与水位相关性较高;当地下水位在基岩层与覆盖层间交替变化或在强风化岩层内变化时,水准与水位相关性一般;但当地下水位在基岩层内变化时,水准与水位相关性则相对较差。
Taking groundwater as the loading and unloading power,the responses of Jinzhou Seismic Sta⁃tion level difference during the period of rise and decline of groundwater level every year is comparative ana⁃lyzed.The results show the high correlation of level difference is achieved when the groundwater level chang⁃es in overburden layer;when the groundwater level changes alternately between bedrock and overburden layer or changes in strongly weathered rock layer,the correlation of level difference is also effective;when the groundwater level changes in bedrock,the results show the poor correlation of level difference.
