A precondition for correctly analyzing the stability of a slope and designing its bracing structure is to study and determine the influence of excavation blasting on the properties of weak intercalation in the layered rock slope. On the basis of in-situ stratification-cracking blasting tests,the properties of weak intercalation were investigated using the LS-DYNA3D program. The displacement distribution and compactness of weak intercalation at different positions away from the charge center and their variou...

1. Introduction The blasting technique is widely used in mining production and in rock excavation for cutting a slope. However, it has many negative effects on the stability of the slope, such as causing a partial or entire strati- fication-cracking in th
