碩士 / 國立臺灣海洋大學 / 河海工程學系 / 103 / Due to lack the related standard of offshore structure design and the experience of offshore geotechnical design in Taiwan, so how to establish the suitable the geotechnical design standard of offshore wind is required. The related offshore wind farm geotechnical design &; ground investigation standard around the world, including ABS, API, BSH, DNV, GL, IEC, NORSOK, Euro code were collected and reviewed in this study. The key point of offshore geological risk is discussed. And the Taiwan local offshore wind farm geotechnical design and ground investigation standard can be establish by review the certain offshore standard and make recommendations for domestic offshore wind farm certification requirement. On the other hand, this study according to the suggestion of geotechnical investigation by the Norsok Standard, the required valuable geotechnical parameters need to investigate is suggested. And according to the offshore wind farm geological section profiles, the reference geotechnical parameters are established.
The geotechnical investigation data of Zhangbin offshore wind farm as in site exploration data and laboratory experimental data were collected in this study. Based on the in situ SPT and CPT with the geotechnical parameters were discussed. Meanwhile, the soil classification was performed by use of soil behavior index (Ic) for Cone Penetration Test (CPT). It could be found that there are many thin layer of soft soil existed in each bore hole. On the geotechnical design stage, the geotechnical problem caused by thin layer of soft soil must be concern with cautions.
