摘要本研究以動力互制因子推導各式配置樁群於垂直向和水平向受力的土層阻抗公式,假設剛性筏基行為,並藉土壤-基礎結構間的勁度關係討論不同群樁效益模式之合理性。本研究發現樁數目愈少,其靜態群樁效益將愈高。在動力分析中,僅樁距與樁徑比值會影響會影響群樁效益,與傳統承載力之群樁效益觀察相符。若振頻為零,研究發現受垂直力之群樁,其靜態效益係數將以塊體模式為最高值;若僅考慮基樁周身土壤支承與考慮筏基影響均導致較高的效益係數,水平向受力樁群其結果相反,效益值以塊體最為保守。兩者情況中,靜態效益值均能滿足設計需求,而較動態效益值係數值為低或類似。;This study analyzes group-pile efficiency in different group-pile arranged forms, using dynamic interaction factor with relation of stiffness between soil and foundation structure. The foundation is assumed rigid and subjected to vertically and laterally exciting forces. The normalized impedance is derived accordingly. Increasing the size and number of piles would drop the value of group-pile efficiency in static. In all the analysis, the ratio of the pile spacing and the pile diameter is found affective to the group pile efficiency. This phenomenon is similar to the conventional observations. At zero operation frequency, it is found that efficiency factor in the block model is higher than the other models with the vertically exciting forces, and the results are contrary to laterally exciting forces where the efficiency factors are conservative with the assumption of the block foundation. In general, the dynamic group-pile efficiency is lower or similar to the static one, therefore the static group-pile efficiency shall satisfy the pile-raft design.
