摘　　要：为了解决实际工程中风积沙路堤的压实与压实度检测等技术问题,以腾格里沙漠穿沙公路为依托工程,通过室内试验、现场试验路分析了振动压实方式、压实遍数等因素对风积沙路堤压实效果的影响,以及风积沙路堤的二次压实效应,提出了风积沙路堤压实技术与压实度的快速检测方法。经工程实践验证:风积沙路堤的压实质量得到了保证;压实度快速检测方法大大提高了检测工作效率。In order to solve the technical problems of compaction and detection of compaction degree of aeolian sand embankment,based on the highway across Tengger Desert,the influence of vibration compaction and passes of rollers on the compaction effect of the aeolian sand embankment was analyzed through laboratory and field tests.Considering the secondary compaction effect,compaction technologies and a method for rapid detection of compaction degree of aeolian sand embankment was proposed.It has been verified by engineering practice that the compaction quality of the aeolian sand embankment is guaranteed,and the rapid detection method greatly improves the efficiency of the inspection.
