Based　on　Novak’s　plane　strain　theory,a　horizontal　vibration　analysis　model　of　the　pipe　pile　partially　embedded　in　viscoelastic　layered　soil　is　established　by　comprehensively　considering　the　influence　of　the　soil　plug　effect　of　partially　embedded　pipe　piles.　The　analytical　expressions　in　the　frequency　domain　of　the　surrounding　soil　and　soil　plug　are　obtained　respectively　by　introducing　the　potential　function　and　variable　separation　methods.　The　analytical　solution　for　the　horizontal　impedance　of　the　partially　embedded　pipe　pile　in　layered　soil　is　derived　by　using　the　pile-soil　coupling　conditions　and　the　transfer　matrix　method.　The　degradation　of　the　obtained　solution　is　compared　with　the　existing　theoretical　solution　to　verify　its　rationality.　On　this　basis,the　influence　of　pile-soil　parameters　on　the　horizontal　dynamic　impedance　of　the　pile　head　is　further　discussed　by　conducting　an　extensive　parametric　analysis.　The　results　show　that:the　horizontal　dynamic　stiffness　and　dynamic　damping　amplitudes　of　the　pile　head　increase　with　the　increases　of　buried　ratio;with　the　increases　of　the　elastic　modulus　of　surface　soil,the　horizontal　dynamic　stiffness　and　dynamic　damping　amplitudes　of　the　partially　embedded　pipe　pile　head　increase,while　the　influence　of　the　middle　and　lower　layers　around　the　pile　can　be　ignored;with　the　decreases　of　soil　plug　length,the　horizontal　dynamic　stiffness　amplitude　of　the　partially　embedded　pipe　pile　head　decreases,while　the　horizontal　dynamic　damping　amplitude　of　pile　head　increases.　©　2023　Nanjing　University　of　Aeronautics　an　Astronautics.　All　rights　reserved.
