| 摘 要： | 为实现土石混填路基压实质量准确、快速检测,基于土石复合介质波动传播特性,导出了通过纵横波速综合反演土石混填路基压实度的波动计算模型。并以瞬态瑞雷波测试为手段对模型路基进行现场波动测试,采集波动数据,计算路基压实度。最后将压实度理论计算值与灌砂法测试结果作对比分析,验证该模型的可靠性。

| Abstract: | In order to achieve the evaluation of the soil-stone mixture embankments,compaction more accurately more rapidly,the volatility model which could be used to calculate the compaction degree with the shear wave velocity and the longitudinal wave velocity was deduced according to the wave propagation characteristics of the soil-stone media.Then the Rayleigh wave testing is taken to collect the wave-data to calculate the embankments,compaction degree.Finally,contrast with the result of the filling sand method t... |
