| 摘要(中) | 摘要 90年7月桃芝颱風造成台灣中部山區嚴重之土石流及山坡地崩塌災害，除了豪雨之影響外，主要係因921地震產生之後遺症所造成。因此，本研究主要對已發生災害之崩塌地，說明崩塌地上源頭「截導水」及「裂縫填補」施工狀況，各類崩塌面穩定工法及蝕溝工法之配置，而下游河道攔砂壩等之興建，應斟酌崩塌地上源頭整治狀況做適度之調整；並建議在震災後，對山坡地整治之工作順序，依時間及緩、急需要，應分二階段進行：第一階段進行療傷工作，即上源頭之「截導水、裂縫填補」工作，在短期內完成，以免除豪雨對崩塌地造成二次災害及下游土石流之發生；第二階段再進行崩塌面上游（崩塌面）、中游（流通區）、下游（堆積區）及河道之整治。 本研究針對中部地區土石流發生區之崩塌現況，依據土壤類別、地形及周遭環境需要，介紹及建議採近生態工法配合傳統工法，由崩塌地上源頭之高點，依坡面高度之順序，分上、中及下游階段，來分別做防制及整治工作。為便於瞭解各不同土質環境、地勢、縱向蝕溝上下游處位等因素，因地制宜配合就地可用材料，採用適應、融合環境之實際整治工法，歸納列表說明；本研究中選擇八種代表性案例，說明土石流防治對策，以及整治實例之研究，提供後人參考。 | |||
| 摘要(英) | Abstract In July of Dec., 2001, Tao-Zhi Typhoon results in serious debris flow and mountainside sloping in mountain area of center Taiwan. The reason of the he impacts besides heavy rain carried by Typhoon is the side effect of the 921 Earthquake. This study investigates the status of “intercept water” and “crack filling” in the upper of slopping area, surveys different kinds of stabilized approach of sliding surface and the allocation of ditching methods. The study finds that it should consider carefully about the rebuild of upper area of slopes for building gravity dam in the downriver zone. It is also suggested the rebuild sequence of mountainside should be separated into two phases. First, applying “intercept water” and “crack filling” methods on upper area of slopes in short time eases the double impacts of heavy rain to slopes. Second, rebuilding sliding surface in upper-river zone, clearing up of passing area of middle-river zone and accumulation of downriver zone helps the whole process. This study investigates the debris flow and slopes status in the center Taiwan. Based on the type of soil, landform and surrounding environment, near-ecological method with transition approach applying on upper-river topper is suggested. The, according to height of slopes, it is recommended to rebuild and protect upper-river, middle-river and downriver zones in sequence. The study also concludes the selection of material used in the rebuilding structure should refer to the environment, type of soil and landform and etc. 8 typical cases studies are also presented in the thesis for reference. | |||
