摘要

考虑到炸药、爆源特征、场地介质等因素,建立了爆破振动分形维数与各影响因素之间相关性的理论分析模型。基于BP神经网络建立爆破振动信号分形维数预报模型,并提出各主要影响因素对爆破振动分形维数影响权重的确定方法,得到了爆破振动信号分形维数相关性的定量描述。研究成果为进一步拓宽分形理论在爆炸与冲击动力学领域的应用范围有重要理论研究意义,对优化爆破技术方案设计,实现降震减灾等具有参考价值。

Abstract

Considering the characteristics of explosive, explosive source and site medium, the theoretical analysis model of correlation between fractal dimension of blasting vibration and influencing factors was established. Based on BP neural network, the fractal dimension prediction model of blasting vibration signal was established, and the method of determining the influence weight of each main influencing factor on the fractal dimension of blasting vibration signal was proposed, and the quantitative description of correlation of fractal dimension of blasting vibration signal was obtained. The research results have important theoretical research significance for further broadening the application scope of fractal theory in the field of explosion and impact dynamics, and have reference value for optimizing the design of blasting technology scheme and realizing earthquake reduction and disaster reduction.
