The　paper　deals　with　the　environment-stimulated　and　vehicle-stimulated　dynamic　tests　carried　out　for　Guangming　steel-concrte　composite　continuous　beam　bridge　in　Fuzhou.　The　theoretical　results　by　finite　element　software　coincide　with　the　test　results　in　situ.　And　the　parameters　in　regard　to　the　composite　action,　cross　brace　effect　and　external　prestressing　etc.　are　analysized　for　further　research　of　dynamic　behavior　and　design　of　the　type　of　composite　continuous　beam　bridge.
