| 以動態行為進行基樁之非破壞檢測，不論在實驗儀器上及理論分析上皆已臻完備。但對於如何將小應變之波動試驗結果轉而估計出實務上最關切之承載力等力學行為，則仍有極大之理論發展及技術改進空間。 阻抗傳遞矩陣為利用four-pole techniques簡諧反應特性所建立之簡易系統動力矩陣，它的表示方式簡單，可利用該系統串聯及並聯之方式將複雜之物理系統加以模擬。另一方面，基因演算法為廣為人知之尋優演算法。利用上述兩種數學工具，本論文嘗試建立基樁波動實驗資料之判讀方法。 本論文主要研究內容為針對IR法所測得之力學導納曲線加以分析，並使用基因演算法試圖尋求資料判讀之機制。吾人希望藉由力學導納曲線資料以及阻抗傳遞矩陣的運算，研究基因演算法潛在之反算能力，找出有效或可行之反算步驟與方式。 |

| Concerning the use of structural dynamics to the NDT evaluation of piles, aspects with respect to experimental facilities and analytical theories are well developed. However, there are still needs in the development of applicable theories and in the improvement of technologies. Transmissibility matrix, derived from four-pole technique, provides an easy way to represent complicated physical systems through the use of serial and parallel connections of simpler dynamic modulars. On the other hand, Generic Algorithm (GA) has been recognized as a powerful tool in searching the best possible solution for many engineering problems. This study intends to use the two mathematical tools to establish an assessment procedure for typical wave propagation or dynamic test data of piles. The main contents of this work contain a thorough analysis based on the traditional IR test data and a proposed back-calculation scheme based on GA’s rules. It is aimed in this study to find out an effective or a potentially feasible procedure for the back-computation of pile parameters from typical transient test signals. |
