摘　　要：为了研究水泥与脱硝双掺改良红黏土在路基工程中的应用,本文选取长度为100m的路基作为试验段进行现场试验研究,分别对改良红黏土进行土工试验、松铺系数、压实度的检测分析。试验结果表明,改良红黏土的压实度达到设计要求需压实7遍,确定了松铺系数及碾压变数之间的关系,且检测的各项指标也都满足设计要求,路基外观平整、无坑洞。In order to investigate the application of cement and denitrification double-admixture modified red clay in subgrade engineering,this paper selects a subgrade with a length of 100m as the experimental section for on-site experimental research.The modified red clay is tested and analyzed for geotechnical tests,loose laying coefficient,and compaction degree.The experimental results show that the compaction degree of the modified red clay reaches the design requirements after 7 compactions.The relationship between the loose laying coefficient and the number of rolling is determined,and all the detected indicators meet the design requirements.The subgrade appearance is flat and free of pits.
