中文摘要 | 面對全球暖化及能源危機的困境,各國皆致力於再生能源的開發。考量能源安全、環保與未來發展,風力發電為台灣最具潛力的新能源之一。然而在政府及民間企業大力推廣風力發電建設之際,台灣於民國97 年9月28 日,受薔蜜(Jangmi)颱風所挾帶之強風豪雨侵襲造成重大災害,位於台中港區的二號風力發電機(風機)塔架也因而倒塌損毀。此乃台灣首次大型風機塔柱攔腰斷裂事件,並無相關前例可循,故其災因研判與分析對爾後類似工程之風險管理愈顯重要。為探討本事故之致災因子及倒塌機制,本文以案例分析法,從專案管理觀點針對工程基本文件進行資料複核與研析。此外,亦統計整理國外類似案例,歸納風機災損事故之災因及潛在風險因子引為殷鑑。本研究根據資料複核結果,從設計風速影響、完整與斷裂螺栓材料強度試驗、風機塔柱3D模型結構分析、法蘭(Flange)接合處螺栓力學行為複核及施工品質管理構面研判可能之致災因子,並提出具體可行之建議與風險防阻措施。研究成果期能應用於實務所需,防止爾後類似工程事故,並回饋利害關係人強化專案風險管理計畫與防災策略。 |
英文摘要 | Wind turbine is one of the most appropriate new sources of renewable energy in Taiwan, which has achieved significant progress in practice by effectively exploiting available natural resources. However, on September 28th 2008, typhoon Jangmi struck Taiwan with strong winds and heavy rainfall that brought down a wind turbine tower located in the Taichung harbor area. The study represents the first attempt to investigate the causes of the collapse of a large-scale wind turbine tower in Taiwan. Based on the site investigation, collected project documents and analytical results, possible causes of tower failure are presented from construction management and technical perspectives. Practical suggestions regarding wind tower risk management and future action plans cover the areas of natural wind effects, re-evaluation of tower structural design, implications of experimental testing of intact and broken bolts, and managerial issues relating to wind turbine tower construction. By applying this study’s findings, project stakeholders can adjust risk management plan strategies, and construction firms can also utilize these findings to provide lessons for future reference. |
