摘要
针对膨胀土的工程特性和胀缩机理,结合具体工程膨胀土路基病害现象,研究了用封闭法填筑膨胀土路基的施工方法,并应用于工程实践,取得了良好的社会经济效益。
According to the engineering characteristics and swell-shrink mechanism,combined with expansive soil subgrade diseases phenomenon of specific engineering,the paper studies the construction method of using closing method to fill expansive soil subgrade,and applies to engineering practice,it achieved good social and economic benefits.
