ABSTRACT:Theshieldmachineinthecourseofshieldtunnelingwillgenerallyrisetogroundsettlementonthetopofthetunnel,andtherewillbeatunnelsettlementintunnelconstructionandoperation,adirectimpactonthesurroundingbuildingsandundergroundfacilitiesinthenormaluse.Itisaveryimportantissueofpracticalengineeringsignificancethathowtoreducetheconstructiondisturbancetosoillevel,analysisofgroundsettlement,andinvestigatethelawsofgroundsettlementinthetunnelconstruction.

Onthebaseofalargenumberofrelevantpapersandliterature,thepaperstudiedmorein-depthonthegroundsettlementcausedbyshieldtunneling.

Firstly,thepapersummarizedthetheoryofourpredecessors,analysisofgroundsettlementresultingmechanism,thefactorsandthegenerallawofgroundsettlement.Secondly,inthebackgroundoftheshieldtunnelingfromGaozengStationtoNewAirportStationinGuangzhouMetro,thepaperanalysiedtheshieldtunnelboringandthegroundsettlementbytunnelingwithfiniteelementsoftwareMIDAS/GTS,thencomparedwithnumericalsimulationresultsandmonitoringdata.Thirdly,stillwithfiniteelementsoftwareMIDAS/GTS,thispaperfocusedonstudyingonhowthefactorsincludinguppercasing,tailshieldgrouting,tunnelingpressureandtwo-lanetunnel'sconstructionprogramaffectgroundsettlement.Finally,thispaperputforwardreasonablepracticalmeasuresonhowtocontrolgroundsettlement.
