Abstract:	本研究考慮基樁動力互制因子影響，推導群樁基礎中之互制單樁波動方程式，納入樁帽。基樁周遭土層支承以p-y曲線土壤彈簧配合轉換阻尼係數模擬，並以 Novak動力阻抗函數之簡易模式分析樁帽周身土壤。研究另以等值墩基方式進行分析。針對群樁中之互制單樁模式與等值墩基分析進行比較。文中並探討群樁間距、土層勁度以及樁長與樁徑比值等參數改變對於基礎反應所造成之影響。 This study establishes the wave equation analytical model for piled raft foundation under the laterally loads. The model of interactive single piles in the pile groups is based on the dynamic interaction factor. Soil spring constants were from by theoretic p-y equations, and the time dependent radiation damping was derived based on the Novak's dynamic impedance functions. Comparative analysis is made with the equivalent pier model. The effects of the spacing ratio, pile-soil stiffness ratio and the pile slenderness ratio on the foundation response are investigated.
