%X 以久马高速公路工程多年冻土路基区段为研究对象，考虑不同的路基土回弹模量检测方法。分别利用贝克曼梁、承载板测定回弹模量两种试验方法测定路基回弹弯沉值，在基于多年冻土路基土在工程设计阶段将两种回弹模量检测方法进行检测，针对本标段已经固化后的路基表面，对两者差异进行分析，并对代表性的测试模量值比较，进行回归换算与对比分析，为供设计与施工参考。<br />
Taking the permafrost subgrade section of the Jiuma Expressway project as the research object, different methods for detecting the rebound modulus of subgrade soil are considered. Two testing methods, the Beckman beam and bearing plate, were used to determine the rebound modulus of the roadbed. In the engineering design stage based on permafrost roadbed soil, the two rebound modulus testing methods were tested. The differences between the two methods were analyzed for the solidified roadbed surface of this section, and representative test modulus values were compared for regression conversion and comparative analysis, providing a reference for design and construction.
