摘要
本文提出了一种既观测地脉动垂直于地面的运动,又观测强迫振动垂直于地面运动的综合地脉动法测定剪切波速度V_s。其传感器组合采用五个垂直传感器组成二维扩展圆形组合和三个垂直传感器组成线性排列组合。该方法不需要钻孔、即能测定地下数十米深范围内以至更深处的V_s地层剖面,是一种经济方便的观测方法。
This paper presents a synthetic microseism method to determine the shear wave velocity Vs. It observes the vertical movement component of microseism as wall as that of the forced vibration. The transducers arrayed in two systems i. e. five vertical transducers composing as a two dimensional circle and three transducers composing as a line. Without borehole,this method can determine the V.-strata profiles within the depths of several tens meters or more. It is an economical and convenient observation method.
