【摘要】 爆破地震动机制复杂,影响因素众多,为找出影响爆破地震效应的主控因素,引入灰色系统中灰色关联理论。通过实例分析,得到了影响爆破地震效应的主次关系,指出钻孔超深、孔网参数是影响爆破地震效应的主控因素,通过优化这些爆破参数是降低爆破地震效应最有效的方法。灰色关联分析方法计算简单、结果可靠、使用简便,在爆破工程中有一定的应用价值。更多还原

【Abstract】 The mechanism of blasting seism is complicated with numerous influencing factors.In order to find out the controlling factors of blasting seismic effect,the grey correlation theory of grey system is introduced.By conducting case analysis,the pecking order influencing blasting seismic effect is obtained;and it is pointed out that the super-deep drilling,pore network parameters are the controlling factors of the seismic effect.The most effective way for reducing the blasting seismic effect is to optimize these blasting parameters.The calculation of grey correlation analysis method is characterized by simplicity,reliable results and convenience for use;so it is of favorable value to the blasting engineering.更多还原
