瑞利波勘探技术在岩土工程勘察中应用

地下介质的弹性波速的差异与介质的岩土力学特征具有很好的相关性,而介质的瑞利波速度与其剪切波速非常接近,因此利用瑞利波勘探技术进行地下介质分层时,其优势十分明显.在岩土工程勘察的初勘阶段可利用瑞利波勘探技术宏观划分力学性质差异明显的地层、地质构造,而在详勘阶段可以探测基岩埋深、填土厚度等的变化趋势,均取得了比较好的应用效果.

THE APPLICATION OF THE RAYLEIGH EXPLORATION TECHNIQUE TO THE GEOTECHNICAL ENGINEERING EXPLORATION

The difference in the velocity of underground media elastic waves is closely related to the geotechnical mechanism characteristics of the media, and the Rayleigh wave velocity is very close to its shear wave velocity. Therefore, the application of the Rayleigh wave exploration technique to the stratification of the underground media has its obvious advantages. In the initial stage of the geotechnical engineering exploration, the Rayleigh wave technique can be used to divide strata and geological structures which have evident differences, whereas in the detailed exploration stage, this technique can be employed to detect the bedrock buried depth and the fill thickness. The application results are satisfactory.
