土地紧张促进电渗近年来在软黏土地基加固中的大量应用,但是对其设计方法的研究却很少。从电渗的机理入手,研究了电渗过程及其电极电解反应;接着分析了土体性质、电极、电源输出和通电方式等四方面因素对电渗固结的影响,并列表总结;随后,综合已有的电渗实例,提出了软黏土电渗加固的设计计算方法;最后举例说明方法的使用。该方法主要面对常见的金属电极长方形布置的电渗处理,经简单改变也能适用其他情况。其优点是能够评价场地的电渗处理适宜性,可以考虑场地地质条件的影响,并且通过控制参数取值范围的方法来提高电渗效率。
Land tensions promote the extensive use of electroosmosis in the consolidation of soft clay foundations in recent years, but few studies have been devoted to its design methodology. From the mechanism of electroosmosis, the electroosmotic process and its electrode electrolysis reaction were studied. Then the influence of four factors on the electroosmosis consolidation, such as the nature of the soil, the output of the power supply and the power supply, Based on the existing examples of electroosmosis, the design and calculation method of electroosmosis reinforcement for soft clay is proposed. Finally, the use of the method is illustrated. The method is mainly applied to the common electro-osmotic treatment of the rectangular arrangement of metal electrodes, and other situations can be applied after simple changes. The advantage of this method is that it can evaluate the suitability of the site for electroosmotic treatment, consider the geological conditions of the site, and improve the electroosmotic efficiency by controlling the parameter range.
