摘要


台灣的地質複雜且地形多變,在這地狹人稠的台灣的山坡地佔全島面積的三 分之二以上,山坡地的穩定性遠比帄地穩定性差,坡地的災害因子不外乎本身的 地質條件差、降雨集中、地下水複雜、溪岸侵蝕、地震。其中又以降雨集中為最 大的危害因子,在台灣海島型國家每年最主要的水資是颱風與梅雨,但應因全球 氣候變遷緣故氣候越來越難以預測,颱風每次帶來的水量都已經超記錄的水量。 然而降雨使地下水上升,而本研究邊坡穩定分析與地下水位與邊坡失穩的關 係與破壞的趨勢。採用更限元素PLAXIS 軟體分析之破壞趨勢,以台北市文山區 的猴山岳為例子,分析其破壞的行為模式。 台北市文山區猴山岳於98 年產生滑動,因本地區地質複雜且在鄰近台北市, 對於台北周圍山區具代表性,本研究以數值分析探討地質與地下水位的關係。

並列摘要


Taiwan is a land of complex geology and varied terrain. Slope accounts for more than two-thirds of the total area of the densely populated Taiwan. The stability of slope is far worse than plain land. Slope hazardous factors are not more than poor geological conditions, concentrated rainfall, complex groundwater, riverbank erosion, and earthquake. The concentrated rainfall is the main hazard factor. As an island, the major rainfall sources are typhoon and monsoon rain. Due to global climate changes, it becomes increasingly difficult to predict the climate. Each typhoon brings about rainfall above records. However, rainfall increases the level of groundwater. This study analyzed the relationships between slope stability, groundwater level, and slope failure as well as the damage trend. With Mt. Houshanyue in Wenshan District, Taipei as an example, this study used the finite element PLAXIS software to analyze the damage trend and the damage behavior model. Mt. Houshanyue in Wenshan District of Taipei produced landslides in 2009. Due to the complex geology and bordering on Taipei as a representative of the surrounding mountainous regions, this study used the numerical analysis to discuss the relationship between geology and groundwater level.
