Ground vibrations are an integral part of the process of rock blasting. The analysis of blasting vibration attenuation is the basis for a blasting risk assessment. To study the influence of rock joints on the blasting vibration attenuation, an autoclaved aerated concrete block was used as a similar material of rock in model tests of blasting vibration propagation. The attenuation process of the blasting vibration was physically simulated. The attenuation behaviors of the blasting vibrations in different directions to joint strike were fitted. Additionally, a positive correlation between the attenuation parameters and the directions was obtained. Furthermore, the Hilbert–Huang transform (HHT) based on the complete ensemble empirical mode decomposition with adaptive noise (CEEMDAN) was used to analyze the vibration velocity signals. The characteristics and variation of the energy distribution were studied in the time–frequency domain. The results showed that the energy amplitude decreased as the propagation distance increased. The energy distribution gradually evolved from concentrated to discrete in the frequency domain. The low-frequency components were always present in the velocity signals at each measurement point, but the high-frequency components constantly changed due to the reflection and transmission of the waves after encountering the joint surfaces. The results of this study provide a reference for the prediction and control of the blasting vibration effect in jointed rock masses.

地面振动是爆破过程中不可或缺的一部分。爆破振动衰减的分析是评估爆破风险的基础。为了研究岩石节理对爆破振动衰减的影响，在爆破振动传播的模型测试中，使用高压灭菌加气混凝土砌块作为岩石的类似材料。物理模拟了爆破振动的衰减过程。拟合了不同方向爆破振动对接头冲击的衰减行为。另外，获得了衰减参数和方向之间的正相关。此外，基于具有自适应噪声的完整集成经验模式分解（CEEMDAN）的Hilbert-Huang变换（HHT）用于分析振动速度信号。在时频范围内研究了能量分布的特征和变化。结果表明，随着传播距离的增加，能量振幅减小。能量分布在频域中从集中逐渐演变为离散。低频分量始终出现在每个测量点的速度信号中，但是高频分量由于遇到关节表面后波的反射和透射而不断变化。研究结果为节理岩体爆破振动效应的预测和控制提供了参考。能量分布在频域中从集中逐渐演变为离散。低频分量始终出现在每个测量点的速度信号中，但是高频分量由于遇到关节表面后波的反射和透射而不断变化。研究结果为节理岩体爆破振动效应的预测和控制提供了参考。能量分布在频域中从集中逐渐演变为离散。低频分量始终出现在每个测量点的速度信号中，但是高频分量由于遇到关节表面后波的反射和透射而不断变化。研究结果为节理岩体爆破振动效应的预测和控制提供了参考。
