摘要

土釘的應用已由發展之初的作為臨時支撐或輔助工程，逐漸也作為永久支撐結構；因此，完善的設計除了靜態分析外，動態特性也必須加以考量。本文先就近幾年土釘應用於陡坡加勁之力學機制與行為之研究予以彙整，並以此為基礎進行土釘加勁邊坡受振時之反應與耐震特性的探討，以供坡地整治時之參考。

Soil nailing has been used successfully in temporary and permanent applications on new and remedial constructions in rural and urban areas. Therefore, the seismic resistance and failure mechanism of nailed slope are worthy of investigation to find a method of stabilizing steep slopes subjecting to seismic strike. Literature on nailed structures emphasizing the mechanical behavior of reinforcement and the interaction mechanism between nail and soil are reviewed. In addition, the seismic response and earthquake resistance of nailed steep slopes are discussed as well.
