摘要(Abstract):

提出了采用有限单元法和多刚体动力学数值仿真方法相结合的仿真技术对框架结构建筑物拆除爆破进行模拟的方法。该技术可对结构的失稳、解体、倒塌运动过程、堆积范围等问题进行预测或再现 ,有助于提高拆除爆破设计方案的安全性和可靠性
The analogous technique for simulating blasting demolition of frame structure,combining FEM with the numerical simulation of rigid multi-body dynamics,is proposed in this paper.Using this technique,the out-of-stable,disintegrating,collapsing and piling processes of the structure can be simulated or reproduced.It is useful for improvement of the accuracy and reliability of blasting plan.
