Consolidation Considering Clogging Effect under Uneven Strain Assumption

In land reclamation projects, the vacuum preloading method has been widely used to strengthen dredged fills by removing water. However, during improvement process, clogging inevitably occurs in drains and soils, hindering water drainage causing inhomogeneous consolidation results. Therefore, it is essential evaluate effect of on behavior slurry at different radii. this study, analytical solutions are derived under an uneven strain assumption calculate zone normal zone, with time-dependent discharge capacity soil considered. Results calculated proposed indicated that slows down development consolidation, reduces final degree, increases difference between consolidations It found influence effect's varies speed decay, value initial drain, permeability, radius zone. Finally, a practical application solution discussed, suggested for calculation when treating high-water-content slurry.
