【摘要】 大量工程实践证明,单一参数的爆破振动安全判据具有局限性和不合理性。采用单一的地面质点振动速度评定爆破地震的安全性,难以准确地衡量爆破振动的危害。除了振动强度之外,振动频率效应也是一个重要因素,同时考虑质点振动速度和振动频率对建(构)筑物的影响才是比较完善的。更多还原

【Abstract】 A great deal of engineering practices have proven that single-factor criterion for the safety measurement of blasting vibration has limitations and then is unreasonable.Taking the particle vibration velocity on the ground as the only one criterion can not measure the blasting vibration hazards accurately.Besides vibration intensity,the effect of vibration frequency is also an important factor.Taking into account both the particle velocity and the frequency of vibration to assess the effects of blasting on nearby buildings is satisfying.更多还原
