碩士 / 國立成功大學 / 水利及海洋工程學系碩博士班 / 101 / Finding renewable energy of sustainable use is the target of many countries in the world. Offshore wind energy is the most important things of developing renewable energy over the past few years in Taiwan. For pile driving of offshore wind turbine generates ground vibrations. These may impact on the surrounding benthos. The maximum soil particle velocity is the standard when a construction being vibrated. Therefore, the thesis use finite element software Plaxis to build up pilot-type numerical model of Taiwan’s offshore wind farm. The attenuation of the ground vibrations about the analysis is nearby the pile driving center. The necessary of setting up the maximum soil particle velocity curve is the pile radius 1m and 2m of pile driving with several piling hammers energy. We can infer the decay about the maximum soil particle velocity happened in 5m to 15m, is far away from the pile driving center. The piling hammer energy becomes bigger, the decay of the distance becomes more obvious. The simulation results can be learned that the pile radius from the soil particle velocity in every distance of the pile driving center doesn’t impact too much. Ground vibrations due to offshore pile driving is the part of Environment Impact Assessment (EIA) in North Hoyle offshore wind farm in England. However, our country has not determined the EIA projects yet, Hope this research can provide assistance while the need of proceeding the EIA.
