The content of this thesis, through the deformation destruction process of th e typical nanlidu landslide along the national highway 318, uses the finite unit a nalysis of computation, revealing the elastic, plastic stress and displacement of each joint inside the slide area pointing out the distribution range of the tension stress and the plastic deformation range, computering the stability safety factor of the slide area, gaining the fixed quantity, quota that evaluates the stability of the slide area, revealing the position of the slide area which is most likely to los e its stability, thus, it can provide theoretic proof for the programs which renova te landslides
本文的研究內容是通過318國道南里渡典型滑坡的變形破壞過程，採用有限元計算分析，揭示滑體內部每個節點上的彈、塑性應力及位移，找出拉應力分佈區和塑性變形區，計算滑體穩定安全系數，得出衡量滑體穩定的定量指標，揭示滑體最可能失穩的部位，從而為滑坡整治方案提供理論依據。 -
