摘　　要：路基压实过程中经常会出现超欠压、部分区域漏压、碾压搭接宽度不够等问题。阐述了采用落球法联合连续智能碾压系统对路基施工质量进行的研究。通过探讨落球法和连续智能碾压系统的技术原理,建立了某公路水稳层回弹模量与压实度之间的关系以及回弹模量与压实模量之间的关系。研究结果表明:上述关系相关性较好,达到0.98以上。当路基的回弹模量达到128 MPa、压实模量达到54 MPa时,其压实度大于96%。通过落球法和连续智能碾压系统的应用,不仅保证了施工质量,而且提升了施工效率,从根本上避免了超欠压、部分区域漏压、搭接宽度不够等问题。In the process of roadbed compaction,there are some problems,such as over-pressure,under-pressure,leakage pressure in some areas,insufficient lap width and so on.This paper introduces the research on the construction quality of roadbed by falling ball method combined with continuous intelligent rolling system.By discussing the technical principle of falling ball method and continuous intelligent rolling system,the relationship between resilient modulus and compaction degree of water-stabilized layer of a highway and the relationship between resilient modulus and compaction modulus are established.The results show that the correlation of the above relationship is more than 0.98.When the resilient modulus of the soil foundation reaches 128 MPa and the compaction modulus reaches 54 MPa,the compaction degree can reach the requirement of not less than 96%.Through the application of falling ball method and continuous rolling system,not only is the construction quality guaranteed,but also the construction efficiency is improved,and the problems such as overpressure,under-pressure,partial area leakage pressure and insufficient lap width are fundamentally avoided.
