The　interaction　mechanisms　of　the　underground　tunnel　passing　through　the　surface　structure　for　a　short　distance　are　complex,　and　there　are　hidden　dangers,　with　the　interaction　between　the　two　tunnels　having　a　nonnegligible　impact　on　the　seismic　performance　of　the　structural　system.　To　explore　the　interaction　law　of　seismic　response　between　the　double　tunnel　and　the　surface　structure,　this　study　conducted　a　shake-Table　test　on　a　surface　frame　structure-soil-double-Tunnel　interaction　system　with　a　basement,　using　an　actual　tunnel　project　in　Zhengzhou,　China,　as　the　background.　A　three-dimensional　(3D)　numerical　model　of　the　system　was　established　using　the　finite-element　analysis　software　ABAQUS　(2021)　with　the　equivalent　linear　method,　and　the　numerical　models　reliability　was　verified　by　comparing　with　the　test　results.　The　verified　numerical　simulation　was　used　to　study　the　interaction　between　the　structures　in　the　system　under　six　different　prototype　model　cases.　The　research　findings　revealed　that　the　tunnels　presence　reduced　the　dynamic　response　of　the　structural　system　while　amplifying　the　far-field　dynamic　response,　and　the　interaction　between　the　two　tunnels　increased　the　degree　of　this　reduction　and　amplification.　The　frame　structure　reduced　the　soil　dynamic　response　while　amplifying　the　acceleration　response　and　shear　force　of　the　tunnel.　Additionally,　the　location　of　weak　layers　of　the　frame　structure　was　influenced　by　the　type　of　seismic　wave　inputted,　while　the　diameter　and　crossing　location　of　the　tunnel　had　nonnegligible　influences　on　the　dynamic　response　of　the　structural　system.　The　research　results　can　serve　as　a　reference　to　preliminarily　determine　the　interaction　laws　of　the　seismic　responses　of　a　double-Tunnel　and　adjacent　surface　frame　structures.　©　2024　American　Society　of　Civil　Engineers　(ASCE).　All　rights　reserved.
