This　paper　focuses　on　the　ground　settlement　induced　by　the　construction　of　a　curved　shield　tunnel.　Ground　loss　and　construction　loadings　are　the　two　factors　causing　ground　settlement,　and　two　corresponding　analytical　models　were　developed.　First,　the　ground　settlement　due　to　ground　loss　was　analyzed　based　on　3D　image　theory.　The　＂integrative　gap　at　shield　tail＂　(IGST)　and　overcutting　gap　of　a　curved　tunnel　were　considered.　Second,　the　ground　settlement　due　to　construction　loadings　was　analyzed　by　modifying　Mindlin＇s　solutions.　The　additional　thrust,　frictional　force,　and　grouting　pressure　were　considered.　Subsequently,　a　case　study　and　a　parameter　analysis　were　conducted.　Finally,　the　obtained　solutions　were　compared　with　a　classical　analytical　solution,　numerical　simulations,　and　monitored　results.　The　proposed　model　could　effectively　predict　the　ground　settlement　in-duced　during　curved　shield　tunneling.
