This　study　develops　an　analytical　model　to　determine　the　settlement　of　a　composite　system　involving　a　pavement　structure　resting　on　a　geosynthetic-reinforced　embankment　overlying　voids.　In　the　model,　the　pavement　structure　is　postulated　as　an　Euler–Bernoulli　beam　on　a　continuous　elastic　foundation,　and　the　geosynthetic-reinforced　embankment　is　idealized　as　an　Euler–Bernoulli　beam　spanning　voids.　The　Winkler　foundation　model　is　revised　to　simulate　the　absence　of　the　voids　under　the　geosynthetic-reinforced　layer,　and　the　corresponding　equations　and　solutions　for　the　composite　system　subjected　to　uniform　loading　are　derived.　The　proposed　solution　is　validated　against　the　existing　theoretical　methods　of　a　dual-beam　on　a　continuous　foundation　without　voids.　The　results　indicate　that　the　existence　of　underlying　voids　has　a　great　impact　on　the　settlements　of　a　composite　system　involving　a　pavement　structure　resting　on　a　geosynthetic-reinforced　embankment.　The　proposed　analytical　model　can　provide　a　theoretical　insight　into　a　preliminary　design　of　a　geosynthetic-reinforced　embankment　overlying　voids.　©　Springer　Science+Business　Media,　LLC,　part　of　Springer　Nature　2025.
