Abstract

The article presents the model study into determination of block medium structure parameters by the seismic sounding method. The modeling was performed on a fragment of a brick wall. The wall was subjected to impulsive loading, and oscillograms of vibration accelerations in certain bricks were recorded. The velocities and spectral structure of waves were determined from the experimental data. The ratio from the earlier one-dimensional experiments, which connects the velocity of a low-frequency pendulum wave, the frequency limiting the wave spectrum and the longitudinal dimension of a block, holds true on the two-dimensional model of the block medium represented by the brick wall. The research findings allow determination of sizes of characteristic blocks in rock mass by the data of seismic sounding.

块介质结构参数估计：砖墙地震测深的模型案例研究

摘要

本文提出了用地震测深法确定块状介质结构参数的模型研究。建模是在砖墙的一部分上进行的。墙体受到脉冲载荷，并记录了某些砖块中振动加速度的波形图。从实验数据确定了波的速度和频谱结构。早期一维实验的比率将低频摆波的速度，频率限制频谱和块体的纵向尺寸联系起来，在以块为代表的块体介质的二维模型上成立砖墙。研究结果允许通过地震测深的数据确定岩体中特征块的大小。
