dc.description.abstract近年來二氧化碳排放問題與溫室效應日益嚴重,導致自然環境受 到重大的破壞,且溫室效應的影響以及用電量與日俱增,進而造成電 力不足的問題日趨嚴重。再加上國際原油供應短缺導致油價高漲,而 臺灣大部分的能源依賴進口燃料進行火力發電,臺灣除了節約能源之 外,急需潔淨而永續的、低汙染的再生能源。因此離岸風機被視為重 要替代能源之選擇,故本研究將以離心模型試驗模擬並探討單樁基礎 受震產生土壤液化時的反應。本研究利用離心模型試驗,模擬臺灣離 岸風力發電機組之單樁基礎的受震反應,在此原則下設計並建造單樁 基礎的縮尺模型。此模型採用二階段縮尺,將現地尺寸折減後再進行 縮尺模型,設計方式為單樁基礎先折減成原型尺寸35%的1g 模型, 再利用尺度定律進行80g 的離心縮尺模型進行離心模型試驗。為了探 討在基礎發生土壤液化時單樁基礎的反應,必須取得土壤完整的動態 參數,將在風機基礎模型中裝設各型的感測器陣列,來了解土壤液化 時地盤反力係數的變化,以及在受震的情況下,基礎土壤側向的抵抗 力、樁身的側向位移、旋轉量及彎矩的變化,探討風機基礎的受震反 應以及基樁設計的安全性。zh_TW
dc.description.abstractIn recent years, the problem of carbon dioxide emissions and greenhouse effect growing, causing great damage to the environment, and the impact of the greenhouse effect and increasing electricity consumption, causing serious problem of power shortage. The international crude oil prices increase is resulting in supply shortages, and most of the energy dependence on imported to fuel thermal power generation in Taiwan, Taiwan in addition to energy savings, in urgent need of clean and sustainable, less polluting renewable energy. Therefore offshore wind turbine is considered an important choice of alternative energy, so this research using centrifuge model test to simulate and study the seismic response of mono-pile foundation when soil liquefaction. In this study, we using centrifuge model test to simulate the seismic response of mono-pile foundation for offshore wind turbines in Taiwan, the design and construction of mono-pile foundation is under this principle. This model uses two-stage scaling, the prototype size reduction to 35% of 1g model at first, and reduction to 80g scale model of centrifuge at second time. To study the response of the mono-pile foundation when soil liquefaction occurs, must to get all soil dynamic parameters, sensor arrays will be installed in wind turbine foundation model, to understand the variation of lateral soil resistance, lateral displacement of the pile, rotation angle and bending moment when earthquake happening, so we can study the seismic response of mono-pile foundation and pile design safety.en_US
