多雨潮湿地区电渗法处理路基过湿填料的研究

Research on Over-wet Subgrade Filler Treatment by Electro-osmosis in Rainy and Moist Areas

根据电渗法脱水的原理,提出了在多雨潮湿地区利用电渗法降低过湿土路堤填料含水率的方法;并结合路基施工情况和电渗脱水的工作原理,研究了过湿土路堤电渗脱水的施工工艺,通过现场试验,探索了路堤填料含水率、电流参数、耗电量、路基压实及沉降等的变化规律,提出了电渗法用于过湿土填筑路基的建议和注意事项。

According to the principle of dewatering by electro-osmosis, this paper presents the method which lowers the water content of the over-wet soil embankment filler by electro-osmosis in rainy and moist areas. Based on sub grade construction and the principle of dewatering by electro-osmosis, the construction technology of dewatering by electro-osmosis in over-wet soil embankment is researched. Through field testing, the change law of water content, electric current parameters, electricity consumption, sub grade compaction settlement and etc in embankment filler are explored, and the suggestion and notice of idling sub grade with over-wet soil by electroosmosis is also put forward.
