摘要
我国现行的《爆破安全规程》中 ,只以爆破引起的质点振动峰值速度这个单一参数作为房屋安全的判据 ,实际上爆破地震波频率特性也是一个很重要的因素。在某次爆破施工中 ,我们以爆破引起的地面质点振动频率规定安全振速来监测楼房的振动、控制爆破施工的规模 。
In the effective China's Blasting Safety Regulations,a single parameter,the peak velocity of particle vibration caused by a blast,is taken as the criterion of building's vibration safety In practice,the frequency characteristic of vibration wave is a very important factor as well In a certain blasting project,the vibration of a building is monitored and the blasting scale controlled on the basis of considering both the peak particle velocity and frequency, thus achieving good results
