以黄泛区国道107线郑州段改建工程为依托，通过对多种改良粉砂土进行击实试验，得到改良土所对应的最佳含水量与最大干密度，并对实验结果进行分析，说明双掺石灰、水泥在增强粉砂土压实度方面的效果更好。结合室内试验结果，利用数值模拟计算，研究交通荷载作用下三种改良土的变形特性，进一步说明了水泥石灰双掺在处理粉砂土路基方面的效果最佳，同时得到最佳掺入比例（3％水泥8％石灰）。

@@@@Based on the flooding area of the Yellow River of National Highway 107 reconstructed project in Zhengzhou,the maximum dry density and optimum water content of improved soil were obtained by beating experiment of improved silt-soil. By analyzing the experimental results,it is indicated that the degree of compaction of silt-soil can be reinforced by using double mixed technology of cement and lime. Based on the results of laboratory test, the deformation property of three kinds of silt-soil under traffic loads was calculated by numerical simulation. The double mixed with cement and lime has the best effect on silt-soil roadbed showed by the results,meanwhile, the results showed that the best of mixing ratio was 3%cement and 8%lime.
