摘要

Through the simulation of explicit dynamic analysis software LS-DYNA,made an analysis to the particle velocity and the stress distribution of surrounding rock when the explosives blasting.Explicated the mechanical character of surrounding rock in the foundation pit blasting,provided a basis to set of blasting parameters and optimized the blasting construction.
