目前,在瑞利面波勘探的资料解释中,主要考虑的是基阶模态面波。然而,在某些地质条件下,很难提取到完整的基阶模态面波频散曲线。高阶模态面波也包含丰富的地质信息,如果只提取基阶模态面波,将会有较大的误差。因此,在实测资料解释中,要综合利用基阶和高阶模态的面波,提取能量最大模频散曲线进行资料解释,才可以提高资料解释的精度。在蜈蚣岭滑坡的探测中,多阶模态瑞利面波的利用取得了很好的地质效果。
At present, in Rayleigh surface wave data interpretation, the main consideration is the fundamental modal surface wave. However, under certain geological conditions, it is very difficult to extract the complete fundamental mode surface wave dispersion curve. High-order modal surface waves also contain rich geological information. If only the first-order modal surface waves are extracted, there will be a large error. Therefore, in the interpretation of the measured data, it is necessary to comprehensively utilize the surface wave of the base-order and high-order modalities to extract the maximum energy dispersion curve of the energy to explain the data, which can improve the accuracy of data interpretation. In centipede landslide detection, multi-mode Rayleigh wave surface utilization has achieved good geological results.
