【摘要】 瑞利波检测被广泛应用于路基工程质量检测中,但对于瑞利波沿三维路基体的传播规律以及对检测结果的影响,尚缺乏深入研究。笔者利用有限差分软件 FLAC3D,对单层介质半无限大体和三维路基体的瑞利波传播特性以及频散曲线进行了数值模拟分析;并与半无限体的瑞利波理论频散曲线进行了对比;讨论了三维路堤边界对瑞利波检测路基路面的影响。更多还原

【Abstract】 Rayleigh wave exploration is widely used in embankment engineering recently, but road embankment boundary effects on Rayleigh wave exploration are not studied thoroughly. Rayleigh wave propagation and dispersive curve in single layers semi-infinite space model and three dimensional road embankment are studied comprehensively by using finite difference software FLAC3D. The results are compared with the theoretical value of semi-infinite space, the effects of three- dimensional road embankment boundary are discussed.更多还原
