Stratum vertical vibration response testing method

The invention relates to a stratum vertical vibration response testing method. The testing method is advantaged in that broadband three-component vibration sensors are arranged on a ground surface inthe stratum depth direction according to set intervals, after receiving vibration generated by a ground seismic source, the three-component vibration sensors transmit signals to a vibration signal analysis instrument on the ground to analyze so as to reflect stratum vertical vibration attenuation characteristics. The method is advantaged in that the method can objectively reflect the vertical vibration attenuation characteristics of an anisotropic stratum, can quantitatively evaluate an influence range of foundation treatment vibration in vibroflotation foundation treatment construction, and has good technical and economic benefits. 本发明是一种地层垂向振动响应测试方法，该测试方法是从地表沿地层深度方向按照设定的间距布置宽频三分量振动传感器，三分量振动传感器接收地面震源产生的振动后将信号传至地面上的振动信号分析仪器并进行分析以反映地层垂向振动衰减特性。本方法能够客观反映各向异性地层垂向振动衰减特性，在振冲地基处理施工中能够定量评价地基处理振动的影响范围，具有良好的技术经济效益。
