To　further　accurately　analyze　the　mechanical　response　of　buried　pipelines　and　pavement　structures　subjected　to　ground　subsidence,　this　study　established　a　dual-beam　model　consisting　of　an　upper　Euler-Bernoulli　beam　and　a　lower　Euler-Bernoulli　beam　to　simulate　pavement　structures　and　pipelines.　The　embankment　fill　layer　and　foundation　soil　were　idealized　as　in　the　Winkler　foundation　model,　which　was　divided　into　three　zones.　Coupling　differential　equations　for　the　behavior　of　this　dual-beam-foundation　system　were　established　according　to　the　force　equilibrium　among　the　pavement　structure,　buried　pipeline,　embankment　fill,　and　foundation　soil　with　voids.　The　stress　distribution　and　deformation　of　buried　pipelines　and　pavement　structures　were　solved　according　to　the　boundary　and　geometric　conditions.　The　proposed　mechanical　model　was　evaluated　on　test　data　and　corresponding　finite　element　codes,　concretely　verifying　the　model＇s　effectiveness,　and　a　parametric　study　was　proposed　to　investigate　the　behavior　of　this　system,　such　as　the　bending　stiffness　of　pipelines,　traffic　load,　the　strength　of　fill　layers,　and　foundation　soil.
