A Constitutive Equation of One-Dimensional Consolidation Derived from Inter-Connected Tests

摘要: ABSTRACT In order to investigate the general relationship between void ratio e, effective stress σ' and time t at any element in a consolidating clay specimen, an inter-connected consolidometer was developed series of experiments on remolded marine conducted. experiments, several thin subspecimens were prepared individual consolidation cells same way, while their drainage channels connected successively. During consolidation, settlement each subspecimen pore water pressure adjacent measured continually, vertical distributions e specimen changes with obtained by calculation. The results showed that e-σ' plane there exists family lines which uniquely corresponds certain value rate e. This constitutive model f (e, σ', ė) = 0 for skeleton further experimentally verified different conditions. Then used as tool explain effects layer thickness compressive strain resulting good agreement simulated experiments. permeability characteristics also examined use experimental data. It found coefficient varies exponentially ratio.
