| 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. |
