| Abstract: | The mainly design principle and determined means of blasting parameters in demolition of Ya-la-he railway great bridge are introduced. According to characteristics of the bridge~(,)s structure,a reasonable blasting program was used,the bridge was disintegrated and smashed by fully utilizing the dead weight when the bridge lost its stability,so that the borehole number was cut down and amount of consumed explosives was reduced,good results of blasting have been achieved. |
