摘要

本文以台灣西部沿岸雲林麥寮回填工業區現地震測試驗相關資料，分析建立剪力波速與深度及標準貫入試驗SPT-N之關係式，並與國內、外學著研究建議關係式比較發現，剪力波速會隨不同區域土層特性而呈現不同之迴歸關係式。為設計理念回歸台灣本土化，於設計沖填工業區振動基礎時可藉由本研究建立以剪力波速與SPT-N值及深度之關係式，推估台灣西部麥寮現地沖積回填土層特性之剪力波速值，以提供回填造地大地工程參數評估與耐震設計之應用。

In this paper, based on the in-situ Standard Penetration Down-Hole sampling and related seismic test data of Mai-Liaw nearshore area of west Taiwan, the relations between shear wave velocity, soil depth and SPT-N value are discussed. Comparisons between the suggested relations by other scholars are also discussed. The results show that, the shear wave velocity would present different regression results for different soil layers. For the design approaches to be localized, the relations between shear wave velocity and SPT-N value are established in this study, The shear wave velocity of reclaimed soil can be estimated with different depths. By using the analysis and evaluation methods the dynamic design of foundations and geotechnical engineering parameters can be evaluated on the reclaimed industrial estates.
