影響邊坡穩定因素中最為重要的因子為降雨,而降雨入滲的行為則被土壤在未飽和帶中的行為所影響,且未飽和帶常見於自然界中,但未飽和帶之分析相當的繁雜,因此本研究使用Geo-studio中的Seep/w模組及Slope/w模組分別模擬降雨入滲及邊坡穩定,分析不同降雨強度在不同邊坡下,安全係隨時間變化的關係,藉此討論降雨強度與邊坡特性對邊坡穩定之影響。
在研究中討論不同的邊坡性質,包括邊坡材料、坡角、坡高、地下水位面及降雨類型,結果得知坡角、坡高及降雨強度越高邊坡越容易產生破壞,而材料的水力傳導係數則決定了降雨時雨水對邊坡穩定的影響程度。而在地下水位面部分,在降雨強度高的情況下改變地下水位面深度對邊坡穩定的影響較不顯著,最後在降雨類型部分,其結果顯示邊坡穩定與尖峰降雨強度出現時間有關。本研究以台北金山鄉三河溪與高雄甲仙小林村已破壞之邊坡進行討論,分析在降雨事件的影響下,邊坡破壞發生的時間,模擬結果在小林村部分相差1個小時而三河溪邊坡則完全吻合。

The rainfall is the most important factor in slope stability, and the rainfall infiltration is affected by the behavior of soil in the unsaturated zone. The unsaturated state is very common in nature, but the analysis of unsaturated zone is very difficult, therefore, we use the Slope/w and Seep/w modules in the Geo-Studio program to simulate slope stability and rainfall infiltration. In this study, we change rainfall intensity and slope condition to get the relationship between factor of safety and time, and discuss the influence of rainfall intensity and slope characteristics on slope stability.
In the study, we discuss the different nature of slope, such as slope material, slope angle, slope height, the groundwater table deep and rainfall patterns. Results indicated that the slope becomes more danger when the slope angle, slope height and rainfall intensity increase, and the hydraulic conductivity of the material determines the impact of the rainfall on slope stability. It has less influence than the rainfall intensity on slope stability when we change the depth of groundwater table depth. In the part of rainfall patterns, the results show that it has great connection between slope stability and occurrence of peak rainfall intensity. In this study, we also discuss the slope failure at the Shanher Stream and the Xiao Lin village, and analysis the slope failure time which are induced by the rainfall. In the case of Xiao Lin village, the simulation result of failure time has an error of one hour, and the result of Shanher Stream is quite consistent with the actual failure time.
