摘要：

To　predict　the　ground　settlement　caused　by　shield　tunneling,　based　on　the　GAP　principle　and　improved　model,　this　study　investigates　the　characteristics　of　the　ground　settlement　induced　by　shield　excavation　using　FLAC2D　numerical　analysis　method.　The　study　results　show　that　with　the　same　shield　diameter,　when　the　tunnel　depth　increases,　the　maximum　surface　settlement　gradually　decreases　and　the　settlement　tank　gradually　widens.　There　is　a　linear　relationship　between　tunnel　depth　and　maximum　surface　settlement.　This　study　results　have　some　reference　value　and　significance　on　the　ground　settlement　analysis　caused　by　shield　tunneling.
