摘要：

Analytical　solutions　of　vertical　dynamic　impedance　and　velocity　response　at　pile　cap　for　vibration　of　friction　pile　in　saturated　viscoelastic　half-space　foundation　were　obtained　and　verified　by　considering　plain　strain　model　and　mixed　boundary　condition　of　pile-soil　interface　as　well　as　effect　of　excitation　frequency　based　on　Boer＇s　porous　medium　theory　for　a　deeper　comprehension　of　its　vertical　vibration　characteristics.　Furthermore,　effects　of　pile　depth　ratio　and　permeability　coefficient　on　vertical　dynamic　impedance　and　velocity　response　at　pile　cap　were　discussed　by　parametric　comparative　analyses.　The　solutions　and　results　of　vertical　dynamic　impedance　and　velocity　response　at　pile　cap　derived　diversified　the　theories　of　pile　dynamics　and　provided　technical　references　and　theoretical　support　for　related　engineering　practice.　©,　2015,　China　National　Publications　Import　and　Export　(Group)　Corporation.　All　right　reserved.
