【摘要】 由直立边坡控制爆破振动测试数据的拟合分析,结合冲击作用下地下管道的动力响应推导,研究了直立边坡控制爆破对地下输油管道的影响。结果表明,爆破塌落体触地时对地面的冲击振动大于炸药爆炸本身引起的地面振动,得出了影响冲击振动强弱的相关因素,并根据分析结果对原有爆破方案进行优化,保证了爆破施工安全与效果。更多还原

【Abstract】 Influence of controlled blasting of vertical slope on buried pipeline was studied by fitting analysis of blasting vibration date and dynamic response derivation of buried pipeline under impact.The results show that the ground vibration caused by collapse was larger than that caused by explosion itself,and the relative factors that affected vibration strength were obtained.The original blasting scheme was improved according to analysis results,which ensured construction safety and blasting effect of the project.更多还原
