分级加载时超固结粘土的一维非线性固结分析
One-dimensional Nonlinear Consolidation Analysis on Over-consolidation Clay under the Stepped Time-dependent Loading
摘要
Abstract
Using the nonlinear empirical models for relationship between the void ratio and both consolidation-pressure and coefficient of permeability, taking into account the effect of stress history of natural saturated clay and stepped time-dependent construction loading, the corresponding governing equations for one-dimensional nonlinear consolidation of over-consolidation saturated clay are proposed. The equations are dispersed using the finite difference method to facilitate solving them. The relevant computer program is developed to solve the equations. The results of one-dimensional nonlinear consolidation and linear consolidation of saturated over-consolidation clay are compared and analyzed.关键词
