    Abstract: 本文擬討論以廣義帽蓋模式(Generalized Cap Model)模擬土壤材料彈塑性於應力分析之計算方 法與步驟。研究中將引用連貫式切線控子 (consistent tangent operator)推導該模式之切線模數, 供結構體應力分析使用。研究結果除與相關文 獻所載之實驗數據比較外,並對該模式於不同 土壤之剪力特徵(shearing characteristics)模擬包括 硬化參數、起始應力以及應力路徑的影響,乃 至與傳統土壤力學之莫耳庫侖破壞參數(c and .phi.)之相對性做廣泛探討。編繹之程式穩定性 以及可信度亦藉有限元素法之實例模擬而加以 印證。
    The Generalized Cap model has been developed to simulate the nonlinear soil behavior under large loads. With the basic model equations, material state can be computed for given strain sets. In this work, derivation of its tangent rigidity matrix on basis of the consistent return mapping algorithm is discussed. Application of the solution in the stress analysis is then presented with an investigation on nonlinear dynamic response of roads.
