中文摘要 | 由於崩塌地崩積之上砂及坡面鬆動之土石,易因地表逕流作用,向下游運移而產生土石流。為了進行崩塌地防治與集水區治理,必須先推估崩塌地區之堆積土砂量,以作為擬定防治計畫之依據。因此,簡便、迅速、精確之推估方法更顯其重要性與必要性。本研究以一均質上體組成之均勻斜坡為對象,基於基腳上方移除而產生直線破壞型態之崩塌地,研擬一崩塌土方量推估方法,並以九份二山崩塌地為例,比較本方法與其他方法推估之結果,顯示本方法之適用性,可作為崩塌地現場初步概估崩塌量之參考。 |
英文摘要 | The loose depositions of landslides are easily eroded and inducive to debris flow. It is necessaryto estimate landslide volume in order to carry on the protective works for the disaster prevention.Therefore, a method which is convenient, speedy and accurate is required to estimate the landslidevolume. Based on homogeneous slope with homogeneous soil, a method for landslide volumeestimation, according to the toe of slope being cut to cause landslide is developed. With an exampleof Chiufenershan landslide, the estimated results by the developed method is compared with othermethods. It shows that the developed method is appropriate and can be used for landslide volumeevalation. |
