Abstract

ABSTRACTThe product performance and drainage effect of electric vertical drains (EVDs) were evaluated by implementing field tests. A small number of electrodes were inserted into the field site and were electrified with different operation modes. The results of the field tests show that the largest range of the current for each pair of electrodes is 1.5–2 A in this dredger fill. A high-concentration salt solution injected into the soil can significantly improve the electro-osmotic drainage effect, for there are no corrosion problems with the electrodes. The electroconductive filter cloth of the EVD does not have much impact on drainage effect and can be replaced by nonwoven fabric cloth. Suggestion is given in this paper that the operation way of electro-osmosis is to provide low energy for the soil in the early stage and then constantly improve the energy when the drainage rate is significantly reduced.
