Nonlinear Consolidation Analysis of Natural Structured Clays under Time-Dependent Loading
Numerous nonlinear theories of consolidation for clay soils have been proposed in the past. Most of them are based on constitutive models of clays whose structural property is neglected, yet the natural structured soils are widely distributed around the world. This study investigated the nonlinear consolidation of natural structured clays using a semianalytical method. Variable permeability and compressibility were considered, as were variable overburden pressure and yield stress with depth and arbitrary loading with time. Simplified models were developed, and the process of consolidation was analyzed in detail. Calculation methods and solutions were determined. Then, a computational program was developed for verification and calculation. The present regressive solutions were found to compare well with the existing solutions, indicating that the solutions are correct and reliable. Finally, the nonlinear consolidation behavior influenced by several factors was investigated using parametric analysis.
