摘要

微差爆破实践中，由于延期雷管通常存在延期误差，不能准确按设计延期时间起爆，导致各分段爆破产生的震动可能发生叠加，引起质点振速超标。尤其是在大规模的微差爆破中，这种因雷管延期误差而产生的震动叠加现象更不容忽视。应用遗传算法对该问题进行了研究，可得到由于雷管延期误差导致震动叠加后的最大可能放大倍数，以此来评价雷管延期误差带来的危害性，可为工程实践中的爆破网路设计和震动控制提供参考。

Abstract

In millisecond blasting

the delay error of detonators can result in possible superposition of vibration induced by separate blasting; and causing transnormal particle velocity. Especially in large scale millisecond blasting

the superposition of blasting vibration can not be ignored. By using genetic algorithm

this problem is studied; and the maximal possible magnification factor of blasting vibration after superposition induced by the delay error of detonators can be obtained. The index of magnification factor can be used to evaluate the hazard of detonators’ delay error so as to offer a reference for the blasting network design and vibration control in engineering blasting.
