【摘要】 基于地震波及干扰信号在覆盖层与基岩分界面的衰减差异实验,分析了基岩类台基对地震波及干扰信号的选择性抑制的机理,提出台基抗干扰品质的概念。在此基础上,以昭通地震台的抗干扰改造为例,给出利用多套地震仪测定台基抗干扰品质的方法。更多还原

【Abstract】 Based on the different performance of seismic wave and disturbance which travel through boundary of overburden and bedrock outcrop,the different attenuating of bedrock outcrop to disturbance and seismic wave is analyzed and verified by experiment.Furthermore,a method for measuring noise immunity of seismic site in simple seismic array is illustrated in the example of Zhaotong Seismic Site.更多还原
