For　the　project　of　pipe　jacking　in　cohesionless　soil,　it　is　key　to　determine　the　vertical　load　on　jacked　pipe　so　as　to　predict　the　jacking　force　accurately.　In　this　paper,　a　new　parabolic　soil　arching　model　was　proposed　to　calculate　the　vertical　load　on　jacked　pipe.　This　proposed　analytical　model　was　composed　of　parabolic　soil　arching　zone,　parabola-typed　collapse　zone　and　friction　arch　zone.　Combined　with　existing　literature,　the　key　parameters　(i.e.,　height　of　parabolic　soil　arching,　horizontal　pressure　coefficient　and　width　and　height　of　friction　arch)　were　determined.　In　addition,　considering　that　the　trajectory　of　major　stress　is　parabola,　the　formula　of　horizontal　pressure　coefficient　was　deduced　in　the　friction　arch.　The　parabolic　soil　arching　zone　is　assumed　as　a　three-hinged　arch　with　reasonable　arch　axis,　and　the　formula　of　load　transfer　was　derived　considering　the　transition　effect　of　parabolic　soil　arching.　The　results　of　experiment,　theoretical　models　and　numerical　model　were　adopted　to　verify　the　proposed　analytical　model.　Finally,　the　influence　of　the　key　parameters　on　the　vertical　load　on　jacked　pipe　were　also　discussed　in　detail.　This　work　provides　a　meaningful　reference　for　evaluating　the　vertical　load　on　jacked　pipe　for　design　of　pipe　jacking.　©　2023　Tongji　University
