    摘要註: 台灣地區年雨量豐沛,每逢颱風季節經常有豪雨發生,常使地下水位升高、邊坡土體浸潤,因土壤含水量與土壤孔隙水壓增高而降低土體穩定度,山區坡地災害頻仍,造成人命財產損失。降雨入滲與地下水滲流,為造成邊坡崩塌的兩個主要水文因子,因此研究降雨及地下水的影響對於了解邊坡破壞的行為相當重要。本研究探討地下水位抬升及降雨入滲對於邊坡穩定及崩塌行為之影響,以自主研發之水文環境試驗箱進行邊坡模型試驗。由試驗結果得知,邊坡破壞多從坡趾發生,而崩塌量與邊坡土體內部含水量分佈、水文因子作用歷時與邊坡土壤粒徑有密切關係。利用試驗土樣之土壤保水特性進行非飽和土壤強度分析,所決定之邊坡安全係數,滿足試驗結果比較。此外,所求得之未飽和土壤水力傳導係數亦合理解釋所得之試驗結果。 Taiwan is an island with abundant of rainfall. The torrential rainfall accompanied with typhoons frequently causes the rise of groundwater level, the increase of slope soil moisture and the pore water pressure so as to degrade the slope stability, result in frequent slopeland disasters and the loss of lives and properties. Rainfall infiltration and groundwater seepage are two of the primary hydrologic factors to slope instability. Therefore, research of the rainfall and groundwater effects on slope failure behavior is very important. In this study, groundwater lifting and rainfall infiltration are investigated through the slope modeling tests using a self-developed hydrologic environment testing box. The test results show that slope failure is initiated from the toe and landslide volume is highly related to moisture distribution inside the slope body, duration of hydrologic effects, and particle size of slope soil. The factor of safety obtained from unsaturated soil strength analysis with soil water conservation characteristics satisfies the comparison of test results. In addition, the obtained unsaturated soil hydraulic conductivities also agree well with the test results.
