This　study　addresses　the　issue　of　localized　ground　subsidence　and　its　effect　on　buried　pipelines.　Timoshenko　beam　model,　placed　on　a　Pasternak　foundation,　is　used　to　analyze　the　internal　force　response　of　buried　pipelines　under　foundation　subsidence.　The　load　on　the　pipeline,　resulting　from　localized　ground　subsidence,　is　assumed　to　be　symmetric.　The　load　distribution　on　the　buried　section　of　the　pipeline　is　represented　using　a　McLaurin　series.　Analytical　solutions　for　the　deflection　and　bending　moment　of　the　pipeline　under　arbitrary　symmetrical　loading　are　derived　based　on　the　theory　of　elastic　foundation　beams.　Additionally,　the　accuracy　of　the　analytical　solutions　is　verified　through　comparisons　with　experimental　studies,　finite　element　analysis,　and　existing　theories.　In　the　analysis,　the　shear　modulus　of　the　Timoshenko　beam　is　set　to　infinity,　resulting　in　the　degeneration　of　the　model　into　the　Euler-Bernoulli　beam.　The　effect　of　the　shear　modulus　and　diameter-span　ratio　(D/l)　of　the　Timoshenko　beam　is　investigated　in　the　parameter　analysis,　and　the　applicability　for　both　beam　models　is　determined.　The　results　indicate　that,　for　buried　pipelines　with　a　diameter-span　ratio　greater　than　0.1,　the　Timoshenko　beam　model　provides　more　accurate　deflection　calculations　than　the　Euler-Bernoulli　beam　model.　©　Korean　Society　of　Civil　Engineers　2024.
