地震振动与爆破振动对建筑物影响的区别与联系

建筑物特别是古建筑物都有可能经历过大大小小的地震,其框架结构,受力支点都有可能有一些改变,如果再加之爆破振动的影响,就有可能使建筑物扭曲变形,甚至倒塌。在爆破震源影响的范围内,结合了地震震动对建筑物的影响后,才能对建筑物的抗震级数做出准确的判断,本文主要从地震震动与爆破振动异同点入手,着重介绍震源位置、传播途径、震波强弱、能量释放方式、峰值速度,最后根据建筑物的框架结构和受力点的受力能力,判断出爆破现场的装药量和应该采用的爆破方式。

Difference and connection of earthquake vibration and blasting vibration influence on building

Buildings,especially ancient buildings are likely to have experienced large and small earthquakes,is frame structure,the fulcrum of the force are likely to see some changes,if we add the impact of blasting vibration,it is possible to make buildings distorted,or even collapse.The impact of the bursting source in the framework of a combination of seismic vibration of the impact of buildings,Anti-seismic buildings can make accurate judgments series,this paper shaking the similarities and differences with the blasting vibration starting point,highlighting the location of the source,transmission,shock waves,strong or weak,the energy release of the way,peak velocity,and finally under the framework of the building structure,the force point of force capabilities,determine at the scene blasting charge volume,it should be used in blasting the way.
