“…Compared with single-point explosion, the propagation law of shock waves are more complex in the two-point and multiple explosion loads. As a sequence, in recent years, many scholars have carried out extensive and in-depth studies on the effect of multiple explosions [ [34] , [35] , [36] ]. For instance, Wang et al [ 34 ] numerically investigated the damage evolution characteristics of the bolt-supported cavern subjected to multiple explosions.…”
