Longitudinal　uneven　settlement　leads　to　changes　of　the　cross-sectional　forces　of　a　long　utility　tunnel,　which　is　also　a　crucial　reason　causing　the　utility　tunnel　structural　damage　and　cannot　operate　normally.　For　the　rectangular　cross-section　continuous　single-compartment　utility　tunnel,　an　analytical　model　of　cross-sectional　internal　force　and　deformation　that　considers　the　shear　and　compression　effects　between　adjacent　sections　caused　by　the　longitudinal　uneven　settlement　was　established,　and　the　model　was　used　to　derive　the　cross-sectional　forces　along　the　utility　tunnel.　Moreover,　the　analytical　results　were　subsequently　compared　with　the　three-dimensional　soil-utility　tunnel　interaction　model　for　validation.　It　is　found　that　the　analytical　model　established　in　this　paper　can　accurately　calculate　the　internal　force　of　the　utility　tunnel　under　the　effect　of　uneven　settlement,　and　the　differences　in　peak　internal　force　of　the　structure　at　key　points　of　the　cross-section　are　less　than　20%　.　It　is　assumed　that　the　longitudinal　uneven　settlement　of　the　utility　tunnel　follows　a　Gaussian　distribution.　This　uneven　settlement　results　in　uneven　additional　bending　moment　and　shear　force　along　the　longitudinal　direction　of　the　structure,　consequently　leading　noticeable　changes　of　the　cross-sectional　forces　of　the　utility　tunnel.　The　proposed　analytical　solutions　of　the　internal　forces　in　the　cross　section　of　the　continuous　utility　tunnel　under　the　uneven　settlement　proposed　in　this　study　can　provide　reference　for　the　structural　design　of　the　utility　tunnel.　©　2023　Science　Press.　All　rights　reserved.
