摘　　要：本文以汝州联通大楼爆破工程实践为背景,通过数值仿真模拟,优化施工方案,研究了楼房倒塌过程中的破坏特征。结果表明:在二层开设切口,同时采用双向微折叠爆破拆除技术能够有效控制建筑倒塌范围,缩短爆堆长度,降低飞石距离和振动速度。大楼实际倒塌过程仿真结果有较高的一致性,通过仿真模拟能够预测倒塌过程及形态。This paper takes the practice of blasting engineering of Ruzhou Liantong Building as the background.By the numerical simulation calculation,it can optimize the parameters of the blasting construction plan,study the damage characteristics in the process of building collapse.The results showed that opening a cut on the second floor and using bidirectional micro folding blasting demolition technology can effectively control the collapse range of the building,shorten the length of the blasting pile,reduce the distance between flying stones and vibration speed.The simulation results of the actual collapse process of the building have high consistency,and the collapse process and shape can be predicted through simulation.
