摘 要: 在公路建设中,虽然将路堤填料取土场放在水库、水塘等低洼地段能够降低建设成本,但是这些地方常有软土分布。目前在高速公路建设中,软土作为路堤填料的处理方法多采用加入生石灰进行改性处理。二次加灰处理软土是新近提出的一种施工方法,该方法不仅有利于生石灰拌和均匀,而且有利于提高灰土处理效果,加快施工进度。为此,本文就其机理加以探讨,仅供借鉴。
关 键 词: 交通工程;公路;软土;改性处理;二次添加灰处理技术

Abstract: In the highway construction, in order to save the cultivated area and cut down the highway cost, the over-water soft-soil at reservoir and pond has always been used for roadbed filling of expressway. For this reason, a new method of two-step quicklime adding for disposing over-water soft-soil is used for highway. This method is not only beneficial to mixing well-distributed quicklime with soft-soil, improving modified treatment efficiency, but also speeding the construction pace of highway. This paper studies the mechanism of this method.
Key words: traffic engineering; expressway; soft-soil; modified treatment; two-step quicklime adding technology
