摘要
通过西安南京铁路合肥南京段高速铁路膨胀土试验段的施工过程控制,对含水量、含灰率,石灰颗粒粒径、改良土颗粒粒径、松铺系数、碾压遍数等施工工艺参数进行了详细的研究。对指导今后高速铁路膨胀土施工有一定的实用价值。
Through the construction control of high speed railway expansive soil roadbed between Hefei and Nanjing city on Xi＇ an to Nanjing railway, this paper researches the construction technology parameters including water content, lime percentage, lime grain size, modified soil grain size, loose laying factor and compression times. The conclusions resulted from this paper have the reference values for expansive soil construction of high speed railway in the future.
