隨著世界能源枯竭及環保意識抬頭，再生能源為當今世界各國最受矚目的發展項目之一，而我國坐擁優良的風場環境，政府亦積極推廣風力發電並頒布「千架海陸風力機」計畫，預計在未來興建大量的風力發電機組，逐步帶動陸域及離岸風電的發展。然而台灣因地理位置的關係，夏季好發的颱風氣候常帶來強風豪雨，近年來造成台灣數起風機塔柱倒塌事故，引發嚴重的經濟損失。在極端氣候的影響下，颱風的強度及好發頻率日益嚴重，探討風機倒塌災因及因應台灣氣候影響的風險防阻措施則越顯重要。本研究藉由蒐集國內外風機塔柱倒塌之案例，探討風力發電機組受強風侵襲而倒塌之觸發機制，研析風機於強風中的作動機制及受力行為，歸納風機倒塌之致災因子，進而運用風險管理之手法，針對風機塔柱受強風破壞及倒塌之肇因，研擬風險防阻之措施，防止爾後類似工程事故之發生。

As energy becomes increasingly scarce and people’s environmental awareness increases, renewable energy has become one of the world’s most highly anticipated areas of development. Taiwan possesses an outstanding wind farm environment, and the Taiwanese government actively promotes wind-power generation (e.g., it has introduced its “Thousand Wind Turbines Project”). In the future, many wind turbines are expected to be built, which will gradually drive the development of land-based and offshore wind turbines. Because of its geographical location, Taiwan is prone to experiencing typhoons that bring constant strong winds and torrential rain in the summer. These natural phenomena have resulted in several wind turbine tower collapses in Taiwan over recent years, incurring serious economic losses. Influenced by extreme weather, typhoon intensity and frequency have become increasingly serious, so identifying the causes of wind turbine collapses and corresponding risk prevention measures (that take into account Taiwan’s climate) have become markedly critical. In this study, domestic and foreign wind turbine tower collapse cases were explored to identify the triggering mechanisms of strong wind-led wind turbine collapses, research and analyze the activation mechanisms of and forces sustained by the wind turbines at these times, and generalize the factors of wind turbine collapse. Subsequently, risk management methods were employed to determine the causes of strong wind-led wind turbine tower damage and collapses, on the basis of which risk prevention mechanisms were developed to prevent these accidents from occurring.
