摘　　要：为探索电渗真空联合预压法对沿海地区深厚软土地基的处理效果与工程应用方法,研究新型电动土工合成材料在电渗真空联合预压法中的应用,进行了实际工程的现场试验。试验设置了不同深度、长度组合EKG排水板的两个试验区,通过将两组试验区与普通真空预压区的处理效果进行对比,验证了与电渗法的联合使用,可在一定程度上缩短真空预压法对深厚软基的处理时间,促进较深层软土的固结,提高对深厚软基的处理效果。In order to explore the treatment effect and engineering application method of electro⁃osmosis combined with vacuum preloading method on deep soft soil foundation in coastal areas,a field test is carried out.Two target areas with different depth and length combinations of EKG drainage boards are set up at the construction site.By comparing the reinforcement effects of the two target areas and the ordinary vacuum preloading area,it is verified that the combined use of the electro⁃osmosis method can shorten the reinforcement time of the deep soft foundation treated by the vacuum preloading method to a certain extent,promote the consolidation of the deeper soft soil,and improve the reinforcement effect of the deep soft foundation.
