The development of new delivery and control systems, particularly in the UK and China, have removed past technical issues experienced in electrokinetic treatment of soils to aid dewatering, accelerate consolidation, enhance soil strength and control pore water pressure and reduced the cost of the method.
In the last decade the economic, environmental and technical benefits, which can be achieved by electrokinetic treatment of soils, have been demonstrated.
The current application areas include: control of pore water pressure; in-situ increase in shear strength; accelerated consolidation of weak soils and marine deposits and dewatering of difficult soils. The presentation will describe the physics of the electrokinetic suite of phenomena and use historic and recent examples to illustrate design and construction with different combinations of electrokinetic effects.
