Shield-soil　rotary　friction　is　one　of　the　reasons　that　cause　asymmetrical　settlements　about　the　central　axis　of　tunnel　center　line.　This　paper　focuses　on　analytical　analysis　of　the　shield-soil　rotary　friction　on　tunnelling-induced　ground　mechanical　reactions.　According　to　the　working　principle　of　the　shield　machine,　the　way　and　process　of　the　shield　torque　acting　on　the　soil　is　proposed.　Based　on　the　calculation　model　of　a　spatial　curved　shield　tunnel　and　the　rewritten　of　the　Mindlin　solutions,　this　paper　derives　the　analytical　solutions　of　the　effect　of　shield-soil　rotary　friction　on　the　soil　displacement　field　and　the　additional　stress　field,　respectively.　The　derived　theoretical　solutions　are　verified　and　compared　with　the　shield　project　of　Beijing　East　Sixth　Ring　Road　renovation　project,　and　relevant　parameters　are　analyzed　in　this　paper.　The　numerical　model　analysis　based　on　the　finite　element　software　and　the　field　monitoring　data　verify　the　correctness　of　the　method　proposed.　The　theoretical　study　in　this　paper　further　improves　the　study　of　the　construction　load　of　shield　machine.　©　2023　Elsevier　Ltd
