中文摘要
邊坡穩定分析採用極限平衡法，可快速得到一潛在滑動面及安全係數，但其假設並未考慮
土壤之實際變形；而有限元素法之優點係採用較合理之土壤行為模式及邊界條件。本研究將採
用極限平衡法之滑動面分析與有限元素法之應力分析分別對有無植生之邊坡穩定性進行比對探
討；研究中顯示植生對邊坡高度較小之邊坡穩定分析有較顯著之貢獻。
英文摘要
The Limit equilibrium method could easily search a critical slip surface and the factor of safety on the slope stability analysis, but the assumption does not take into account the actual deformation of the
soil. Applications of the finite element method can reflect the actual soil behavior and the boundary conditions of the soil-structure interaction. The limit equilibrium method of the sliding surface analysis
and finite element method of stress-strain relation were to compare for the unplanted and planted soil on the slope stability analysis. The results show that the planted soil in small height of slope has more
obvious contribution on the slope stability analysis.
