  •   樁基礎設計對工程師來說,是相當繁雜冗長的。由於電腦科技與個人電腦不斷的更新與發展,藉由個人電腦來處理複雜的計算問題將會更加的精確有效率。此外,藉由實務經驗與理論發展不斷的演進,讓我們對於樁基礎的分析與設計上有了更清楚明確的認知。基於此,發展出一套基樁分析與設計程式是相當重要與有效率的。本程式之建立主要依據由內政部營建署於2001年所頒佈之『建築物基礎構造設計規範』。基樁之容許承載力主要由下列三者之最小值來決定:(1)樁體本身之強度;(2)地盤之強度;(3)樁軸直角方向力(樁頭位移之限制)。經由樁基礎分析步驟之程式化,我們可以快速有效率的得到地盤承載力、樁頭位移量與各樁體之最大應力。再由鋼筋混凝土柱的強度設計法的設計概念來設計任意一根基樁所需要的最小鋼筋量。最後,我們將會介紹幾個基樁分析實例來與此程式做比較。由比較結果可以發現此程式之數值結果相當可靠。本文中針對樁基礎設計所發展的程式,不但可提供使用者對於樁基礎設計步驟有基本之學習,同時能有效率的得到樁分析與設計的結果。

      The design of pile foundation is often complicated for civil engineers. For the advancement of computer science, it will be more efficient to deal with complicated calculation using computers. In addition, with the accumulation of practical experience and the advancement of the theory about pile foundation increasingly, we have even more explicit knowledge to analyze and design pile foundation. For this reason, to develop the computer software of analysis and design of pile foundation is more and more important. The establishment of this software is mainly according to “Foundation of Structure Design Specification 1 Edition” published by Construction and Planning Agency, Ministry of the Interior (CPAMI) in 2001. The capacity of a pile is decided by the minimum value of the followed there conditions: (1) the strength of pile, (2) the strength of the stratum and (3) the allowable horizontal displacement. With the stylization of the analytic procedure, the capacity of the pile, the displacement of the pile head and the internal stresses can be gained quickly. Furthermore, the program of reinforced concrete can obtain the needed minimum steel ratio. Finally, some examples of pile analysis will be introduced to compare with the numerical results. With the results of difference, we can find the numerical results are reliable. The pile design program in this thesis will provide the users with basic study about pile design procedures and meanwhile help them to get the outcomes of pile analysis easily.
