為配合國家再生能源政策，我國政府積極推動離岸風力發電之規劃開發。因我國前期大型海洋工程施工案例較少，且對於我國西部海域地質與地工資料掌握程度較低，致使我國離岸風場開發存在地質災害風險與開發成本不確定性。一般為降低離岸風場開發風險，風場開發商多於離岸風場開發前，以離岸風場角隅4點及中心點之少量鑽探資料進行開發可行性評估及概念設計，考量我國前期離岸風場開發實務經驗不足，以少量之鑽探資料恐難達成達成概念設計目標，透過建立場址完整之海域工程地質模型，可望提高概念設計成果可信度，釐清風場開發地質災害之風險。
依德國聯邦海事局(BSH)之建議，離岸風場於設計開發至施工維運各階段皆需進行海域地質調查，以滿足離岸風場各階段所需之地質資訊，以確保施工、運轉期間安全；本研究透過蒐集彰濱地區圓錐貫入試驗(CPT)成果，參考Robertson(2010)建議之土壤分類方法透過CPT取得之地工參數進行土壤行為指數計算，並依土壤行為指數分佈區間進行土壤分類，再利用地理資訊軟體建置彰濱地區工程地質模型，並將SPT-based工程地質模型[張倖偉(2017)]與CPT-based工程地質模型進行比對，說明以不同鑽探資料建置工程地質模型土層分佈之差異；各土層之地工參數資料則透過克利金法給定，將工程地質土層幾何分佈模擬結合克利金地工參數推估權重，可提供離岸風場三維土壤地質分佈資訊，供我國離岸風場海域地質調查規劃、地質災害評估及開發設計重要參考。

In order to cope with national renewable energy policy, government institutions have actively promote the offshore wind energy recently. Because of the lack of offshore environment information, the risk of geotechnical hazards are the challenges to offshore wind project developer and engineer unit. During development of our offshore windfarm, feasibility assessment is usually performed by borehole data at 4 corners and central point of offshore windfarm. Owing to lack of experience, engineer designers are hard to achieve concept design. To reduce the risk of offshore windfarm development, it is necessary to establish the ground model of Taiwan offshore wind farm.
Ground investigation is necessary in every phase of offshore wind farm development to satisfy the soil information and ensure the security during the construction and operation phases. The study completed 3D ground through the standard penetration test(SPT) and the cone penetration (CPT) result in Chang-Bin area. Due to the unknown soil classification from CPT in site, the study used the soil classification method proposed by Robertson (2010). In the study also compared the difference between SPT-based ground model and CPT-based ground, and figured out the reason causes this discrepancy. After completing building ground model, assigning the corresponding geotechnical parameter to each soil layer through kriging method would been done in the study. The 3D ground model can be used for geological investigation planning, soil disaster assessment, and assist the windfarm developer to meet the demand for conceptual and basic design
