RISAnalysis on Large-Strain Nonlinear Consolidation of PVD-Improved Soft Soils with Non-Darcian Flow Considering Variable Well Resistance and Vacuum Pressure
Publisher: ASCE
Abstract: The deviation of water seepage from Darcy’s law has been verified in soft soils with high compressibility. Consolidation behaviors of prefabricated vertical drains (PVD)-improved soft soils caused by non-Darcian flow have ...
Solutions for One-Dimensional Rheological Consolidation of a Clay Layer with Threshold Hydraulic Gradient under Multistage Loading
Publisher: ASCE
Abstract: For clays with low permeability, some experimental results show that there may exist a threshold hydraulic gradient, below which the water in clays cannot flow. This threshold hydraulic gradient induces a moving boundary ...
Nonlinear Consolidation Analysis of Stone Column Composite Foundations Considering Radial and Vertical Flows within the Stone Column and the Variation of Well Resistances
Publisher: American Society of Civil Engineers
Abstract: The clogging effect caused by installing stone columns is depth dependent. The movement of soil particles into the stone column, which is induced by the consolidation of soils, further resulting in a clogging effect on the ...
