中文摘要 | 本研究結合擴散模型與平流模型,建構適合描述現地的邊坡演化模型,探討邊坡變化量、 邊坡後退形態與模擬邊坡演化過程,並以現地邊坡測量及數值高程地形進行案例分析。本研究 引用的邊坡演化模型可用於描述減坡後退與平行後退的邊坡後退形態,以台中市大坑礫石邊坡 為演化案例,擬合其邊坡演化形態,求得相關模型係數,並提出非均質邊坡演化模擬方法。本 研究僅探討台中大坑地區單一邊坡的演化情形,其結果顯示近幾年該邊坡演化屬於減坡後退。 |
英文摘要 | This study coupled the diffusion and advection model to establish an evolution model for description of slope evolution, including amount of slope movement, slope retreat and simulation of slope evolution processes. The field survey of the specific slope and digital terrain models were used for case study. The slope evolution model adopted in this study can be used to describe the evolution of slope decline and parallel retreat. For the case study of the gravel slope in Da-keng, Taichung, we simulated the slope evolution for obtaining model coefficients and proposed a method for simulation of the non-homogeneous slope. This study only analyzed a specific slope evolution of the Da-keng test site in Taichung. The result revels that the specific slope evolution should be better classified as slope decline in recent years. |
