The　fault　zone　plays　a　vital　role　in　the　internal　force　responses　of　the　tunnel.　An　analytical　solution　of　the　tunnel　under　the　fault　zone　creeping　is　developed　by　taking　account　of　normal　and　tangential　interaction　between　the　ground　and　tunnel.　First,　the　elastic　foundation　beam　model　is　used.　Wherein,　the　normal　interaction　is　considered　by　applying　the　displacements　of　the　free　field　on　the　distal　end　of　normal　foundation　springs.　And　the　tangential　interaction　is　transformed　into　bending　moment　applied　on　the　beam.　The　analytical　solution　of　the　tunnel＇s　response　is　gotten　based　on　the　model.　Secondly,　the　numerical　solutions　from　finite　element　model　of　3D　are　provided　to　verify　the　validity　of　the　proposed　analytical　solutions.　Finally,　the　effect　of　the　fault　zone　width,　the　elastic　modulus　of　the　fault　and　the　concrete＇s　grade　of　the　lining　are　investigated.　The　results　show　that　with　the　width　of　the　fault　zone　increasing,　the　internal　force　decrease.　The　concrete＇s　grade　of　the　lining　has　opposite　effects　on　the　internal　force　of　the　tunnel.　And　with　the　growth　of　the　elasticity　modulus　of　the　fault　zone,　the　shear　force　and　bending　moment　increase　and　decrease,　respectively.　©　2023
