质点振动速度与主振频率在爆破监测中的应用
|
摘要
通过分析爆破振动对结构的破坏机理,提出了用质点峰值振动速度和主振频率作为爆破振动的监测方法,并探讨了结构的破坏准则和部分国家的振动安全标准,以及影响爆破的因素,进而对爆破采用有效控制。
In this paper,the peak particle velocity and main vibration frequency are put forward as a monitoring measure of blast vibrations based on the analysis of blast vibrations damage to the structure.In this paper,the damage criteria and the safety standards of vibration in some countries are shown.In addition,this paper analyzes the influence factors of the blast and give suggestions on effective control of the blast.
