The　numerical　simulation　analysis　of　adjacent　building　vibration　induced　by　urban　subway　transit　is　made　under　simple　and　multiple　support　excitation,　and　is　compared　to　experiment　and　analysis　in　situ.　The　results　show　that:　(1)　about　the　adjacent　building　vibration　induced　by　urban　subway　transit,　the　numerical　simulation　analysis　under　multiple　support　excitation　is　more　close　to　in　situ　experiment　and　analysis　than　under　simple　support　excitation;　(2)　floor＇s　vibration　is　mainly　expressed　floor　slab　vibration,　and　the　amplified　vibration　between　floors　mainly　concentrate　to　the　low　band　below　20　Hz.;　(3)　the　numerical　simulation　analysis　should　consider　the　damping　effect　of　ground　vertical　vibrations　induced　by　urban　subway　transit　in　building,　as　far　as　possible　to　adopt　the　theoretical　mode　under　multiple　support　excitation,　which　can　get　more　objective　and　scientific　analysis　conclusion.　©　2011　IEEE.
