摘要
电渗固结法可以短时高效地提高地基承载力,且不会产生地基失稳现象,是针对软土地基应用前景较好的地基处理方法。结合国内外研究现状,简要介绍了电渗法的加固机理,着重分析了电势梯度、通电方式、电极材料与布置形式、土壤含水量、含盐量及pH值等因素对于电渗固结过程的影响。综述了电渗法的试验研究与数值模拟研究进展。基于目前电渗法国内外研究现状,指出电渗法存在的问题,并对其未来发展进行了展望。
Electro-osmotic consolidation is a good ground treatment method for soft soil.It can improve the bearing capacity of the foundation in a short time and efficiently,and it will not produce the phenomenon of foundation instability.Combined with the research status at home and abroad,this paper briefly introduces the reinforcement mechanism of electro-osmotic method,and emphatically analyzes the influence of electric potential gradient,electrification mode,electrode material and arrangement form,soil moisture content,salt content and pH value on the process of electro-osmotic consolidation.The experimental research and numerical simulation of electro-osmotic are reviewed.Based on the current research status of electro-osmotic in home and abroad,the existing problems of electro-osmotic are pointed out,and the future development is prospected.
