摘要:
为提高爆破减震措施的减震效果并降低工程造价，提出将减震沟和减震孔进行组合的综合减震方法。采用LS-DYNA动力分析软件从爆破振动速度、频谱特征以及应力云图3个方面对减震孔、减震沟以及综合减震措施的减震效果进行对比分析。研究结果表明：综合减震措施在水平径向和垂直向上的减震率相对最大，分别达81.91%，75.74%；综合减震措施由于减震孔的存在，对爆破地震波高频成分的滤波作用优于减震沟措施；综合减震措施下部的减震孔会继续阻碍应力波的传播，进一步削减应力波能量，从而达到保护隔震屏障后方建（构）筑物安全的目的。
Abstract:
In order to improve the damping effect of blasting damping measures and reduce the project cost,a comprehensive damping method combining the damping ditch and damping hole was proposed.The LS-DYNA dynamic analysis software was used to compare and analyze the damping effect of the damping hole,damping ditch and comprehensive damping measure from the perspectives of blasting vibration velocity,spectral characteristics and stress nephogram.The results showed that the comprehensive damping measure had the relatively largest damping rates in the horizontal radial and vertical upward directions,reaching 81.91% and 75.74% respectively.Due to the existence of damping hole,the filtering effect of comprehensive damping measure on the high-frequency components of blasting seismic waves was better than that of damping ditch measure.The damping hole at the lower part of the comprehensive damping measure would continue to hinder the propagation of stress wave and further reduce the energy of stress wave propagation,so as to achieve the purpose of protecting the safety of buildings and structures behind the isolation barrier.
