By　mean　of　the　vibration　testing　measurement,　accelerator　of　vibration　and　its　spacial　varied　features　of　the　soil　and　rock　slope　located　in　316　State　Road　due　to　the　traffic　loads　were　analyzed;　moreover　the　vibration　wave　signals　were　analyzed　by　FFT;　and　frequency　spectrum　characteristics　of　vibration　wave　were　obtained.　The　results　show　the　information　reflected　inherent　characteristics　it　carried　during　vibration　wave　propagation.　The　vibration　response　of　soil　and　rock　slope　is　equivalent　sensitive　due　to　traffic　loads;　the　accelerator　and　amplitude　of　vibration　of　the　soil　slope　is　greater　than　that　of　rock　slope　under　same　loads.　The　vibration　response　of　the　soil　slope　is　decreases　little　by　little　from　up　to　down　along　the　slope　and　its　attenuation　is　compared　fast　in　short　distant;　but　the　vibration　attenuation　of　the　rock　slope　is　compared　slow　in　short　distant.　Main　frequency　moves　to　low　frequency　with　vibration　wave　transmitting.　The　testing　result　will　offer　reference　for　analyzing　propagated　pathway　of　vibration　and　its　influence　on　the　stability　of　slope.　Furthermore　it　is　of　practical　meaning　to　the　evaluation　of　slope　stability　caused　multifarious　factors.
