摘要

本文旨在介紹一簡易且有效的樁基礎動力分析方法。該方法係以基樁之波動方程式為基礎，將樁群互制與樁帽的影響納入分析中，同時亦可融入各項設計參數與變數，以因應實務需求。所適用的工程問題可涵蓋樁基振動行為、承載特性以及耐震設計。其結果與有限元素分析所得相似，但可大幅節省分析時間，使工程師易於完成最佳設計方案。

A simplified and effective analysis is introduced to monitor dynamic behaviors of the pile foundations. The method based on wave equation of the piles can simulate the effects of the cap and the interactive piles as well as other design parameters. The applicable subjects may include the pile responses due to the superstructure loads, the foundation capacity and the seismic design concerns. Corresponding results are found similar to the FEM ones, however it is more efficient for the engineers in making the optimized design solution.
