n view of bedding cracks and back cracks caused by blasting excavation in bedding rock slope,this paper puts forward the calculation method of stability coefficient of bedding rock slope formed by blasting.Based on the measured data of bedding rock slope of Yu-Huai railway,the stability analysis of the slope influenced by blast effect is made,and the calculation shows that blast effect decreased the self-stability of slope and the decrement is up to 54%.Then some blasting excavation and protection methods for bedding rock slope are put forward.This provides theoretical basis for the optimization design of blasting excavation of bedding rock slope.
