    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
    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
    應以及基樁設計的安全性。;In 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.
