分析爆破拆除高耸建筑物倒塌触地产生的危害:触地震动、触地飞石和超压气流。基于一般塌落质点振动速度公式,提出3种减少震动危害的措施;根据抛体运动规律,得出触地飞石水平飞行范围,提出3种减少触地飞石危害的措施;在分析超压气流危害机理的基础上,提出了3种减少超压气流危害的措施。并引用实例进行分析说明。 Analysis of the damage caused by the collapse and collapse of towering buildings caused by blasting: touchdown vibration, touchdown flystone and overpressure airflow. Three kinds of measures to reduce the vibration hazard are put forward based on the formulas of the vibration velocity of normal slump particles. According to the law of projectile movement, the horizontal flight range of the touch-sensitive rock fly is obtained, and three measures to reduce the hazard of the touch- Air hazards on the basis of the mechanism proposed three kinds of measures to reduce the harm of overpressure air flow. And reference examples for analysis.
