摘　　要：为了成功探测到微小的引力波信号(~10^(-19)m),地面激光干涉仪引力波探测器需要降低对其影响的各类噪声.本文概述引力波探测器受地面震动噪声的影响以及隔离地震噪声的基本原理和方法.目前,多级悬挂系统和主动隔振系统被用来降低引力波探测器的地面震动噪声.通过对LIGO,Virgo,KAGRA以及GEO600的悬挂和隔振系统的详细介绍,本文深入了解被动隔振和主动隔振方法在地面引力波探测器中的应用.To successfully detect the ultrasmall gravitational wave signal(~10^-(19)m),the ground-based laser interferometric gravitational wave detector should reduce all kinds of noise.This study summarizes the seismic noise that affects gravitational wave detection and the basic principle and method for mitigating the seismic noise.At present,a multistage suspension system and an active vibration isolation system are combined to further reduce seismic noise.We investigate and analyze the application of passive and active vibration isolation methods in ground-based gravitational wave detectors by reviewing the suspension and vibration isolation systems of current gravitational wave detectors,including LIGO,Virgo,KAGRA,and GEO600.
