摘要


本研究是針對臺灣地區大規模岩體滑動之案例與岩體滑動量體之推估方法,討論各種推估方法的適用性。以過去重要五個大規模岩體滑動案例之滑動面積、體積及土方量等調查資料,以面積-深度或面積-體積幂次關係等兩種方法推估滑動體之體積,發現均有低估的現象。有鑑於此,本研究重新定義大規模岩體滑動之規模,利用案例之滑動土方量及崩塌面積資料發展一新面積評估法。其結果顯示新面積評估法呈現二次多項迴歸式,且R^2=0.97,可作為未來對於滑動面積30公頃至400公頃岩體滑動之簡易體積評估方法。

並列摘要


This study focuses on landslide volume evaluation methods and their applicability to large-scale landslides. Historical data from six large-scale landslides were used to estimate landslide volumes by power-law formulas (area versus depth or area versus volume). The results show the estimated volumes are undervalued. A new landslide volume evaluation method was carried out to improve the precision of the landslide volume evaluation. This method was created by landslide area and volume from the historical records and is shown in terms of a polynomial regression equation with an R-squared value of 0.97. The landslide areas among 30 ha and 400 ha were verified to properly fit this equation and will be utilized as the simple estimation method.
