A full-scale field trial of electrokinetically enhanced cohesive reinforced soil using electrically conductive geosynthetics

The use of cohesive fill in reinforced soil construction is not permitted by most design codes, including the current British Standard on reinforced soil BS 8006: 1995. This paper reviews a full-scale field trial utilising electrokinetics to improve the strength of reinforced cohesive fill in situ within a reinforced soil wall, allowing construction with a material that is currently classified as unsuitable. In the trial the cohesive till was dewatered using horizontally placed electrokinetic geosynthetic electrodes and drains at an applied potential difference of 30 volts within a conventional, sandbag faced, wraparound reinforced soil wall. Results show that the fill within the electrokinetically treated zone of the structure was significantly improved, resulting in a stable structure. For the covering abstract see ITRD E125786.
