摘要
既考虑材料非线性又考虑初始有效应力沿深度变化的一维固结问题，由于其求解的复杂性，解析解 很难求得，一般的解答都是采用数值方法获得。作者建立了求解初始有效应力沿深度变化的软粘土非线性一维固 结问题的半解析方法，编制了计算程序，并通过详细的计算，得到了有关孔压和沉降曲线，然后通过分析比较， 对软粘土地基非线性一维固结性状进行了探讨。
Owing to the difficulty of deriving analytical solutions for one - dimensional consolidation problems of soils taking into account of the effects of nonlinear stress - strain relationship and initial effective stress distribution, almost every author studied the complex one-dimensional consolidation theory using numerical methods before. In this paper, the semi-analytical solution for one dimensional nonlinear consolidation considering the initial effective stress distribution is presented with computer program developed. Based on the computation results, some useful consolidation and settlement diagrams are prepared and the relevant one-dimensional nonlinear consolidation behavior of soft clay is discussed.
