dc.description.abstract | 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. | en_US |
