黄土土壤中爆炸成坑作用的力学参数分析

爆炸是研究土壤动态破坏特性和地下土壤振动波传播规律的重要方法，因此需要分析土壤爆炸作用的一些力学特征参数。由于土壤介质的复杂性和多样性，很难有统一的方法预测这些参数。针对我国渭河滩黄土土壤，通过试验研究爆炸波引起的黄土土壤爆炸坑洞的形成和振动传播规律测量，结合土中爆炸力学的理论分析结果，给出黄土土壤爆炸作用的特征参数的估算方法，为相关分析提供参考。

Analysis of Mechanical Parameters of Blast Hole Formation in Loess Soil

A lot of researches about the underground soil dynamic damage characteristics and the soil vibration wave propagation law are making by using explosion way,so we need to analyze the mechanical characteristic parameters of explosion in soil.Due to the complexity and diversity of the soil medium,it is difficult to have a unified method to predict these parameters.In view of loess soil of Weihe in our country, the method to estimate the relative parameters were given by measuring parameters of vibration wave propagation caused by blast wave through experimental study way,and combined with the analysis results of the explosion mechanics theory in loess soil,to provide reference for correlation analysis.
