This　paper　carried　out　vibration　tests　on　three　typical　road　sections　along　a　subway,　and　analyzed　the　regulation　of　vibration　attenuation.　The　conclusion　is　that　the　60-80　Hz　weight　of　environmental　vibration　of　subway　is　stronger　than　other　weight,　and　the　weight　transmitted　to　structures　is　mainly　dominated　by　frequency　below　20　Hz;　the　vibration　in　vertical　weight　attenuates　more　slowly　than　in　horizontal　weight,　and　the　amplitude　in　vertical　weight　is　higher　than　that　in　horizontal　weight;　there　exists　a　vibration　amplifying　zone　in　a　certain　distance　to　subway　track,　which　is　determined　by　the　geological　condition,　the　depth　of　the　tunnel　and　mechanism　of　vibration.　The　distance　is　20-30　m　away　from　subway　track;　the　energy　were　mainly　within　10　Hz　in　the　vibration　amplifying　zone,　and　high　frequency　vibration　weight　could　attenuate　with　the　increase　of　distance,　although　some　could　magnify　under　certain　geological　conditions.　Finally,　the　attenuation　empirical　formula　was　given　to　predict　subway　environmental　vibration,　which　could　be　used　for　reference　in　vibration　control　and　buffer　design　of　the　ground　structure.
