针对爆破振动引起的一系列危害,采取科学合理的爆破振动控制措施有着重要意义。根据爆破振动衰减理论,从爆源条件和传播途径两个方面分析了爆破振动影响因素,并总结了几种爆破振动控制技术在理论、实验与数值模拟方面的研究情况。结合不同破坏机制下的爆破振动安全判据研究现状,指出现阶段爆破振动研究的发展方向:建立快速、准确的爆破振动优势因素评价系统;利用三维数值模拟方法分析建筑结构易损构件;制订具有人性化的爆破振动安全标准;开发基于无线网络技术的爆破振动智能分析系统。

In view of a series of harms caused by blasting vibration,it is of great significance to take scientific and reasonable blasting vibration control measures.According to the theory of blasting vibration attenuation,the influencing factors of blasting vibration are analyzed from blasting source conditions and propagation path.Then the research of several blasting vibration control techniques in theory,experiment and numerical simulation are summarized.Combined with the research status of blasting vibration safety criterion under different failure mechanisms,the development direction of blasting ...
