| 摘要(中) | 省道台14線係通往草屯、國姓、埔里、霧社之最重要公路，公路沿線邊坡易受颱風豪雨或地震之影響而發生崩塌，對人民生命及財產之安全影響重大。先前現地調查發現在此路段之31K~75K間有13處易發生崩塌的邊坡。本研究利用ArcView
3.X地理資訊系統建立此公路沿線的地理資料庫，利用GIS空間分析的技術，求出資料庫中有關地形、地質…等邊坡崩塌潛勢之影響因子。將各因子分類等級並求其所佔面積和崩塌面積，統計網格分佈情形，以相對量化分級之概念，求各等級之計量值。並以崩壞百分比的離散情形計算各因子的權重值，將公路沿線的山崩潛感程度，分為穩定、低、中低、中、中高、高潛感共六級。製作公路沿線的山崩潛感圖，以供相關單位參考；最後探討各因子對邊坡發生崩塌的影響程度，再針對公路沿線13處易崩塌邊坡進行防護的優先順序提出建議。 由研究結果發現，坡度與高程兩因子對本研究區域邊坡穩定影響最大；埔里盆地以西，大部分區域為低潛感至中潛感區；埔里盆地內，大部分為穩定區域；埔里盆地以東，大部分的區域為中潛感至高潛感區，又高潛感區多位於山脊位置。檢核結果顯示：不安定指數法預測崩塌地準確率良好，實際崩塌地落於中高潛感以上區域者達92%。 | |||
| 摘要(英) | The
14th provincial highway is a major road connecting Taichung,
Tsautun, Kuohsing, Puli and Rem-ain townships. Slope failures induced by
typhoons, heavy rain, or earthquakes not only paralyze traffic but also
cause severe damage in property and threaten lives. Previous
investigation indicated that there are thirteen slopes failed regularly
along the 31~75K section. The main objective of this study is to find
out the failure potential of slope in this region. With the aid of
ArcView 3.X, a Geographical Information System (GIS) software,
geographical and geological factors that influence the failure potention
of slope were quantified. Slopes inside the study region are classified
into zones of stability, low, medium, medium high, and high failure
potential. Results of this study indicate that inclination and elevation are the two most important factors influencing the failure potential of slopes. West of the Puli basin , most of the shopes are classified to have low to medium failure potential. The Puli basin is located inside the stable region. Most of the slopes east of Puli basin have medium high to high failure potential. Compared with results of field investigation, 92% of the 13 regularly fail slopes located in the zones of medium high and high failure potential. | |||
