摘　　要：基于电磁能装备的电爆破在基坑工程中有巨大应用前景。提出了基于脉冲电源-电爆炸负载阵列的协同破岩技术,通过多应力波叠加实现大体积硬岩可控电爆破。分析了电爆炸过程中过电压产生机理以及多阵列协同过程中的过电压传递特性,提出了强流开关的过电压抑制方法。分析了单电爆炸负载与阵列协同破岩的作用效果,双电爆炸负载阵列单位体积破岩能耗为单电爆炸负载的38%,表明电爆炸负载阵列协同可有效实现大体积硬岩的可控电爆破。Electric blasting based on electromagnetic energy equipment has great application prospects in foundation pit engineering.This article proposes the synergistic rock breaking technology based on pulse power supply and electric explosion load arrays,which achieves controllable electric blasting of large volume hard rock through the superposition of multiple shock waves.The article analyzes the mechanism of overvoltage in the process of electric explosion and the mechanism of overvoltage conduction in the multi-array collaborative process,and proposes the overvoltage suppression method.It compares the rock breaking effects of single pulse power supply and multi-array and the specific energy consumption of the dual load array is 38%of a single load for rock breaking,which indicates the electric explosion load array can effectively achieve controllable electric blasting of large volume hard rocks.
