| 摘 要： | 根据重庆沿江高速公路工程中遇到的高液限土实际情况，选取3组试验土样详细分析了高液限土的物理性质，然后针对公路工程质量控制指标 CBR展开试验研究，分析了高液限土 CBR与含水量、饱和度、击实功之间的关系，通过室内实验，综合各方面因素以求获得较大的强度 CBR进行路基填筑，并首次提出“黄金含水率-合理击实功体系”的概念。将含水率控制在22．5％～27％范围内，在3＆#215;55～3＆#215;70击实功下可获得较大的强度CBR值。

| Abstract: | This paper selected three groups of high liquid limit soil test soil samples analyzed the physical properties of high liquid limit soil.The project is the highway engineering from Yushe to Heshun in Shanxi province.Then,we launched a pilot research for highway engineering quality control indicator-CBR.We analyzed the relationship between the high liquid limit soil CBR and moisture content,satura-tion,compaction power.We first firstly proposed out the concept of“Golden moisture content-reasonable compaction work system”.If the moisture content is controlled within the range of 22.5% to 27% and obtain in 3 ＆#215;55 ~3 ＆#215;70 compaction function,we could obtain a larger intensity CBR value. |
