摘　　要：现有路基工程质量检测方法直观可靠 ,但也有费工、费时、成本高的问题 ,因此只能在有限的测点上对路基进行检测 ,难以连续全面地反映路基的质量。为克服这一问题 ,本文对碎石路基填料的夯实程度与弹性波速的关系进行了试验研究 ,从而为利用波动参数对路基的施工质量进行检测奠定了基础。在此基础上 ,应用波动方法 。The existing methods for testing the construction quality of road base are expensive, in terms of both labour and time, though they are direct and reliable. As a result, they can only be applied on limited measuring points, and can hardly reflect the quality of the whole road base continuously. In order to solve this problem, the relationship between the tamping degrees and the elastic velocities of road base materials is studied in laboratory. The study result can provide the physical foundation for the test of road base construction quality using wave propagation method. It is psooible to carry out the continuous and overall test of road base construction quality by wave propagation method.
