运营公路路基黄土的粒度成分研究

通过对临潼～渭南高速公路和312国道甘肃段不同交通量的路基黄土做比较研究,提出了适合公路工程的细粒土的粒度界限,并在此基础上,总结了黄土路基中粘粒、粉粒、砂粒含量的变化规律,建议黄土路基的填筑应采用级配良好的黄土填料。

Research of the Granularity Composition of the Loess

Compare the loesses of roadbed of different traffic volume: LinTong to WeiNan superhighways and Gansu section of 312 National Freewayses. puts forward a boundary of the tiny particle soil of the in keeping with highway engineering, on this foundation,tallied up the regulation of the variety of the content of the grain, the powder grain, the sand grain in the loesses of roadbed , suggested its should adopt the class to go together with the good loess filler.
