本文给出了对共振现象出现概率的理论分析与实验数据间关系的思考。样品取自位于半空间的硬化粗质冻土地基,包括石质冻层。参考从三个场地14次地震记录的纵、横波速求得的土层相对频率特征,进行了对其共振频率的评估。纵、横波速在前贝加尔和后贝加尔地区的粗质冻土层中随湿度和温度而变化。将这些概括化的速度值与一个共振频率和纵、横波度之间的关系式结合起来,用于评估被调查土层的纵、横波速的概率值。结果显示,通过综合在实验室尺度获得的速度值和现场测量获得的速度值的数据,则利用地震记录波来确定在松散土层内传播速度的概率值是可能的。
In this paper, the relationship between the theoretical analysis of the probability of resonance phenomena and experimental data is given. Samples were taken from hardened frozen ground found in half-space, including stalactites. With reference to the relative frequency characteristics of the soil obtained from the longitudinal and transverse wave velocities of the 14 earthquakes recorded at the three sites, the resonance frequency was evaluated. Longitudinal and transverse wave velocities vary with humidity and temperature in the coarse permafrost zone in the regions of Pre-Baikal and Post-Baikal. Combining these generalized velocity values with a relation between resonance frequency and longitudinal and transverse wave degrees, is used to assess the probability values of longitudinal and transverse wave velocities of the investigated soil. The results show that it is possible to use the seismogram to determine the probability of propagation velocity in a loose soil layer, by combining the velocity values obtained at the laboratory scale with those obtained on site.
