瑞雷波法在高速公路高填台背病害检测中的应用

Application of Rayleigh Wave Method in Highway Back Disease Detection of High Filling Station

利用瑞雷波在不同介质中传播时的频散特性及其传播速度与介质的关联性,采用面波仪对某高速公路高填台背病害进行了检测,得到了桥头路基不密实区的位置及范围,为注浆处治提供了依据。处治结果表明,瑞雷波检测法具有较高的准确性,工程实用性良好。

Taken advantage of the relevance of frequency characteristic as well as propagation velocity of Rayleigh wave in different media and media, this paper uses surface wave instruments to conduct disease detection of high filling station for certain highway, concluding that the location and range of less dense area of the bridgehead roadbed, which provide basis for the grouting treatment. The treatment results show that Rayleigh wave detection has high accuracy and practicability.
