| Summary: | 碩士 === 朝陽科技大學 === 營建工程系碩士班 === 91 === 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.
