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 foun-dation pit blasting, provided a basis to set of blasting parameters and optimized the blast-ing construction.
