The Newcastle University research output collection, currently available on ePrints, will shortly be moving to a new open repository platform, Figshare. To prepare for the data migration we have paused adding new content to ePrints, and will resume once the new repository is launched. During this time you will continue to have access to ePrints (but no new content will appear). We will share updates here when available.

Abstract

The effect of combined electro-osmosis and preloading was investigated to accelerate drainage and consolidation progress in soft subsoil clay with low permeability. Experiments of electro-osmotic consolidation under voltages ranged from 0 to 20 V and constant loading of 75 kPa were conducted, and the osmotic effluent was monitored from various London clay samples. The results show that the volume of osmotic effluent increases in the cathode and decreases in the anode with the total osmotic effluent increasing. The osmotic effluent from the anode is independent of voltage, and the coupling of loading and electro-osmosis increases the effluent from the clay, especially for high voltages.
