摘　　要：利用自制模型在室内进行一维电渗试验,通过4组试验对比研究不同通断比的间歇通电模式对电渗加固滩涂淤泥的影响.通过对比试验过程中的排水量、抗剪强度、含水率、电极腐蚀强度表明:间歇通电可有效减缓电极腐蚀,改善土体抗剪强度,提高电渗效果;间歇周期不宜过长,建议通电2 h间歇15 min.Four laboratory tests for soft clay in the shape under intermittent current were conducted on electro-osmotic consolidation apparatus developed by authors. Currents and drainageswere monitored every certain time during the test,while the distributions of shear strength and water content weremeasured after the test. The results suggest that with appropriate power on period and time ratio,current intermittence can result in lighter electrode corrosion and enhance electro-osmosis efficiency excessively,with the optimal power on and off period being 2 h and 15 min respectively.
