针对水城水钢集团治理技改工程中爆破拆除80 m高冷却风机烟囱的振动监测结果,分析其塌落触地震动特点,给出了震速回归方程,认为塌落体的塌落触地震动是危害地面受保护对象的主要能源。实践证明,爆破拆除所采取的高烟囱塌落触地减震堤坝措施可以有效降低塌落触地震动速率。 Aiming at the vibration monitoring results of blast furnace demolition 80 m cooling chimney in blasting demolition in Shuicheng Shuigang Steel Group Management Technical Renovation Project, the characteristics of contact vibration of collapse are analyzed, and the regression equation of velocity is given. It is considered that the slump ground contact vibration is Main energy sources that endanger the protected objects on the ground. Practice has proved that blasting demolition adopted by high chimney collapse touchdown damping dam measures can effectively reduce the slump touchdown vibration rate.
