摘要
提出了现行路基承载力评定方法存在的问题,通过介绍落锤式弯沉仪(FWD)和动态圆锥贯入仪(DCP)使用原理及各自优缺点,运用FWD和DCP结合工程实例对路基承载能力进行对比评定分析,得出了两者评定路基承载能力的可靠性和相关性.
The current testing problem in carrying capacity of subgrade is raised. Then the working principle of Falling Weight Deflectometer and Dynamic Cone Penetrometer as well as both advantages and disadvantages are introduced respectively. Using FWD and DCP to assess the carrying capacity of subgrade, a practical engineering case is analyzed. From the results, the reliability and relativity of them in which assess carrying capacity are compared.
