摘　　要：为了确定全厚式道路水泥改良土路床各检测指标的可靠性和相关性,采用FWD、PFWD、DCP等现场检测手段对施工质量进行检测。结果表明,弯沉值与铺筑厚度、水泥土龄期有良好的相关性。贯入度和动态回弹模量在厚度40 cm时相关性最佳,相关系数均在0.7以上。在后续施工质量检测中,动态变形模量和贯入度作为非常规指标,可用于全厚式道路路基压实质量的评价。In order to determine the reliability and correlation of the detection indexes of the full-thickness road cement improved soil roadbed,the on-site detection methods such as FWD,PFWD and DCP are used to detect the on-site construction quality.The results show that the bending settlement value has a good correlation with the paving thickness and soil age.Penetration and dynamic resilience modulus have the best correlation when the thickness is 40 cm,the correlation coefficients are all above 0.7.The dynamic deformation modulus and the degree of penetration can be used as non-conventional indicators to evaluate the compaction quality of full-thickness road subgrade in the subsequent construction quality inspection.
