中文摘要 | 阿里山森林鐵路常因颱風、豪雨、地震等因素,發生山崩、地滑及土石流等災害。2009年莫拉克颱風重創臺灣,所帶來的超大豪雨亦造成阿里山森林鐵路多處路段之邊坡坡體發生大規模的崩塌。本文選定二處災害較嚴重之路段,藉由地質調查、鑽探及現況調查災害分析,研判崩塌機制,擬定可行之治理規劃,以作為復建工程設計之參考。二萬坪崩塌區之岩層傾向與坡向相同,形成順向坡,為老舊崩塌地,崩塌類型屬大規模且深厚崩積層滑動,以及地表逕流沖蝕之複合型破壞。而多林崩塌區之岩層傾向山體,與坡向相反,形成逆向坡,惟因節理發育且連續性佳,與坡面形成岩楔,易造成崩落,崩塌類型主要為岩盤崩解、崩積層滑動及逕流沖蝕之複合型破壞。調查結果顯示,此二區之崩塌規模甚大,不易進行全面性之植生復育與坡面保護,故建議鐵路復建均採用隧道方案避開崩塌區,以達避災、防災及永續經營之目標。 |
英文摘要 | Alishan Forest Railway frequently suffered landslide, landslip and debris flow caused by different natural hazards. During Typhoon Morakot, several large landslides occurred. In this study, two severe damaged sections were selected as the pilot areas. The geological investigations were conducted to investigate the failure mechanisms. The first selected area is in Erwanping which was an old landslide area with dip slope. The failure mechanisms of this collapsed area include deep landslide in colluvium material and erosion. The second selected area is the collapsed area in Duolin area. The rock joints in the slope formed rock wedges which fell down easily. The failure mechanisms of this collapsed area include decomposition of rock stratum, deep landslide and erosion. After a comprehensive discussion, the tunneling transportation is chosen because it's a better way to pass through the collapsed areas and the maintenance of the tunnel is much easier in these collapsed areas. |
