摘要
针对南水北调东线工程中产生的大量高含水量疏浚淤泥处理难的实际工程问题,通过外加生石灰的方法对高含水量疏浚淤泥进行了改性处理,将高含水量疏浚淤泥处理成了一种可以作为淤泥堆场围堰、河堤培土加固等实际工程填土材料的松散良质土.室内试验结果表明:添加生石灰处理高含水量疏浚淤泥时,改良土塑性指数随着掺灰比的增加而降低;在同一掺灰比下,原泥初始含水量低的生石灰处理土的塑性指数比原泥初始含水量高的生石灰处理土低;处理土塑性指数的改变主要发生在龄期的前3 d.
A great quantity of waste dredged North Water Diversion Project in China. Its clayey soil is generated by the construction of the Eastern Route of South-to-proper disposal is therefore an important issue. A new method has been be useful as fill material in cofferdam and dike engineering. Laboratory tests have also been performed on the treated soil with the following results： the plasticity index of the treated soil decreases with the increase of quick lime content; when the quick lime content remains constant, the plasticity index of the treated soil with higher initial water content is larger than that of the treated soil with lower initial water content; the decrease in the plasticity index of the treated soil occurs mainly in the first three days of curing.
