结构中爆炸泄入坑道工程内部空气冲击波传播试验研究

Experimental research on air shock wave propagation inside the tunnel caused by explosion in a structure

目前结构中不同侵彻深度爆炸研究主要集中于结构的震塌破坏,而对结构毁伤后的泄漏冲击波效应研究极为有限。为获得结构毁伤后泄漏冲击波传播特性,针对装药量、埋深、钢筋配筋率、混凝土基体强度和有无结构等影响因素共进行了48次试验,揭示了这些影响因素对泄漏空气冲击波超压强度的影响规律。

At present,the research on explosion with different penetration depths in structures is mainly focused on spallation of structures,while the research on the effect of residual air shock wave after structural damage is quite limited.In order to obtain the propagation characteristics of residual shock wave after structural damage,48 tests have been carried out on the influence factors of charge weight,burst depth,steel reinforcement ratio,basic strength of concrete and the presence or absence of the structure,etc.,revealing the influence law of these influential factors on the residual air shock wave overpressure.
