摘要
炸药装药的土中爆炸波的传播和衰减规律是个很复杂的问题。由于土壤介质的复杂性和多样性,很难有统一的方法来预测其力学参数,如爆炸振动波的传播速度、土壤的动态力学特性和土中弹道的介质特性等;但这些力学参数在爆炸波衰减、破坏区域和土中弹道计算中,却是非常重要的;因此有必要给出它们的分析方法。针对我国渭河滩黄土土壤,研究爆炸波引起的土壤振动传播规律及力学参数的问题,以便为相关工作提供理论参考。
The blast wave propagation and attenuation law of the explosive charge in soil is a very complex problem. Because of the complexity and diversity of the soil medium,it is difficult to have a unified method to predict the mechanical parameters,such as the dynamic mechanical properties and blast vibration wave propagation velocity in the soil,ballistic features in soil media,but these mechanical parameters is very important,in which the explosion wave attenuation,destroy region and ballistic calculation in soil,so they are the necessary for giving the analysis method. This work aimed at China’s Weihe beach loess soil,study the problem on soil mechanical parameters and vibration propagation law of blast wave in soil caused by explosion,so as to provide the theoretical reference for the relevant work.
