近年來，對於基礎建設的保護往往是邊坡災害的重要議題之一，可能的原因有地震、暴雨或其他人為活動所引起之邊坡災害。本研究即在探討由地震引起的邊坡擾動，分析軟體以RS2作為分析，其原理以有限元素理論，但邊坡在破壞後後期的行為較無意義，所以本研究欲探討出邊坡可能開始破壞的時間點。根據前人的研究，Hoek-Brown破壞準則較Mohr-Coulomb破壞準則更可提供較好的岩石邊坡穩定性分析，於是本研究採取Hoek-Brown作為分析的依據。此外，本研究採取了傳統Newmark方法和強化Newmark方法，用來判斷邊坡可能破壞時間點，當作參考依據，在與動態分析結果作比較，最後，以2008年汶川地震造成的大廣寶邊坡山崩為例作為分析驗證。

In recent years, slope disasters have become a critical issue for infrastructure protection. They can be caused by the earthquakes, rainfall, and other human activities. This study discusses slope disturbance induced by earthquakes. All the analyses were conducted using RS2 software version 9.0. It is based on the finite element theory. This study is expected to explore the possible time of the slope’s failure. According to previous studies, the Hoek-Brown failure criterion provides better rock slope stability estimations than the conventional Mohr-Coulomb failure criterion. So this study uses the Hoek-Brown failure criterion. In addition, this study also adopts the traditional Newmark and the enhanced Newmark methods to investigate the possible time of slope failure. Finally, this study uses the Daguangbao landslide caused by the Wenchuan earthquake to discuss the results from different methods.
