中文摘要 | 本計畫之目的在於調查雪霸國家公園內及其大眾化步道受九二一地震影響之情況,並提出對策。本國家公園大眾化步道有二,即:雪山步道和大霸步道;本報告將雪見區司馬限林道列入,故共有三條。 本計畫調查九二一地震引發的四種災害類型,即:震、裂、崩、土壤液化,並調查其分布範圍。分析結果認為國家公園係在強震區之北緣,受影響的類型只有「崩山」一項,其範圍侷限雪見區老松山至大雪山區小雪山之陡坡區。 本國家公園三條大眾化步道皆不在受影響之地區內,並大部分靠近地勢稍緩之嶺線,除大霸尖山下係通過經常性崩塌地之外,其他路段未受九二一地震之顯著影響,因此無須採取特別之防範對策。 |
英文摘要 | The present study aimed at surveying Shei-pa National Park especially the three public trails within to see if they were ever affected by the 921 earthquake in 1999, in central Taiwan. The very earthquake caused ground surface ruptures, ground motion, landslides and liquefaction in middle western Taiwan and caused tremendous disaters. Field studies showed that Shei-pa National Park was just outside the northern reach of that strong earthquake, and hence only its south-west part was affected with landslides occurring on steep slopes. As the three public trails run mostly along the ridges that are somewhat gentler than other parts of the mountain, therefore, no striking damages were observed of these trails. |
