摘　　要：为解决在定向爆破建筑物拆除过程中,施工时间长、难度高、作业危险系数大等问题。用数学建模模拟仿真被拆除物在爆破时的受力状况,分析不同爆破点的位置和不同起爆顺序产生的位移和反力。结果表明,由于爆破点位和起爆顺序的不同,其爆破后的效果不同,从中选出最优方案进行施工,减少了人工计算时间,增加了定向爆破的安全可靠性。采用数学建模模拟仿真技术对定向爆破的拆除物进行模拟仿真具有可行性。To solve the problems of long construction time,high difficulty,and high operational risk in the demolition process of directional blasting objects,mathematical modeling is used to simulate the force conditions of the demolished object during blasting,analyzing the displacement and reaction forces generated by different positions of blasting points and different detonation sequences.The results show that the selection of different blasting points and the setting of different blasting sequences can result in different effects after blasting.An optimal plan is selected for construction,which reduces manual calculation time,and increases the safety and reliability of directional blasting.It is feasible to use mathematical modeling simulation technology to simulate the demolition objects of directional blasting.
