| Abstract: | Reinforced concrete brace beams were demolished by blasting in the beam plant near Beijing-Shanghai high-speed railway which was being constructed.For minimizing blasting risks caused produced by blasting vibration and blasting sky rocks and so on,the initiation network of out hole and in hole delay time was adopted,and the maximum amount of explosive detonated at one time was controlled strictly.The blasting demolition of the project was successful and reached desired blasting effect.Its successful experie... |
