To　predict　the　settlement　of　low　reinforced　embankments　on　soft　soil　foundation　with　high　accuracy,　the　pavement　structure　is　modelled　as　a　Euler-Bernoulli　beam,　and　the　reinforced　embankment　is　simulated　as　composite　materials　and　simplified　as　Timoshenko　beams　considering　the　lateral　shearing.　The　soft　soil　foundation　is　simulated　by　the　three-parameter　Kerr　elastic　foundation　model　considering　the　stress　diffusion.　To　derive　the　governing　differential　equations,　the　energy　balance　equation　is　developed,　and　the　principle　of　stationary　total　potential　energy　is　used.　Based　on　the　eigenvalue　differential　method,　the　differential　governing　equations　of　settlement　deformation　of　embankment　are　derived,　and　the　analytical　solutions　for　the　settlement,　shear　stress　and　bending　moment　of　reinforced　embankment　on　Kerr　foundation　are　established.　The　effects　of　the　thickness　and　the　elastic　modulus　of　soft　soil　foundation　and　the　reinforcement　position　on　the　stress　and　settlement　of　the　reinforced　embankments　are　analyzed.　The　results　show　that　the　Kerr　foundation　model　can　simulate　the　settlement　of　reinforced　embankments　with　higher　accuracy　than　Winkler　and　Pasternak　models.　©　2019,　Science　Press.　All　right　reserved.
