摘要
以往的爆破震动安全判据通常只考虑了质点峰值振动速度这个单一参数 ,实践和监测成果表明这一判据是有缺陷的。在列举并讨论国内外相关安全判据的基础上 ,指出制定爆破震动安全判据时必须同时考虑质点振动速度和振动频率两个参数。
Former safety criteria of blasting vibration only take the particle vibration velocity(PPV) into account, but both practices and measured data monitoring demonstrate that these safety criteria have limitation. In this paper, some safety criteria adopted in practice are presented and discussed, and it is proposed that both particle vibration velocity and vibration frequency should be taken into account in safety criteria for blasting vibration.
