臺灣地區離岸風機套筒式基樁承載特性分析之研究 摘要 本研究針對臺灣西部海岸離岸風機套筒式基樁承載特性進行分析。由於臺灣地理位置特殊位於環太平洋地震帶，地震活動十分頻繁，因此，離岸風機基礎在地震下之穩定性評估為重要之研究課題。此外，本研究針對海事工程有效應力孔隙水壓激發模式、海事工程土壤與流體耦合分析模式進行研究，以利風機基礎結構分析設計。臺灣西部海域離岸風場工址多屬海床沈積層，土層主要以砂土與黏土層為主，且一般較為鬆軟，因此，本研究提出一套新的離岸風機基礎設計流程，而離岸風機套筒式基樁之靜力與動力承載力分析是重之重點研究課題之一。由分析成果顯示，本研究之基礎設計分析可適切掌握土壤與基礎之互制行為，孔隙水壓激發模式能有效地模擬土壤液化現象，配合風機設計載重能檢核樁基礎承載力是否滿足設計需求，並利用動力分析得知基礎受震後之行為。 關鍵詞 : 動力分析、 孔隙水壓、海床土壤、離岸風場 、套筒式基礎 引用文獻 Cheng-Yu Ku*, Lien-Kwei Chien (2016), “Modeling of Load Bearing Characteristics of Jacket Foundation Pile for Offshore Wind Turbines in Taiwan”, Energies 2016, 9 (8), 625; doi:10.3390/en9080625.
