Research　purposes:　The　metro　is　under　construction　in　a　city,　in　order　to　get　credible　prediction　accuracy　for　vibration　response　of　neighboring　constructions　with　this　city　metro,　it　is　necessary　to　develop　systematic　research　on　environmental　vibration　along　this　city　metro　with　comparatively　special　geological　condition.　Accordingly,　two　subsystem　model,　the　vehicle-track　coupled　model　of　vertical　vibration　and　the　tunnel-soil-construction　models　of　3D　FEM　are　established　base　on　third　kind　of　soft　soil　site　of　this　city.　Vibration　responses　of　neighboring　constructions　are　predicted　reference　to　the　parameters　of　this　city　metro.　Research　conclusions:(1)　Vibration　responses　of　neighboring　constructions　mainly　reflect　structural　self-vibration,　while　there　are　rebound　zones　of　middle-high　frequency　in　the　low　levels　of　the　constructions.　(2)　Train　speed　and　single-double　track　have　significant　effects　on　peak　acceleration,　but　have　no　significant　effect　on　the　vibration　shape　of　the　constructions.　(3)　The　horizontal　distances　from　multistoried　construction　to　the　centerline　of　the　two　tunnels　is　within　5　m,　middle-highrise　and　highrise　constructions　are　within　10　m,　or　range　from　30　m　to　40　m　in　vibration　amplification　zone,　or　the　metro　train　speed　is　over　60　km/h,　the　floor　accelerations　of　constructions　may　surpass　vibration　limit　of　related　specification,　so　further　vibration　control　is　required　to　apply.　(4)　The　relevant　research　results　can　provide　atheoretical　and　technical　support　for　design,　construction　and　vibration　control　of　metro　environmental　system　on　this　city　or　geological　condition　similarities.　©　2017,　Editorial　Department　of　Journal　of　Railway　Engineering　Society.　All　right　reserved.
