双曲冷却塔底面大，重心低，站立稳定，爆破拆除难度大，采用动力有限元分析程序LS-DYNA对其爆破拆除倒塌过程进行了模拟，模拟结果与实际倒塌过程非常接近。实践证明，通过合理选择参数和计算模型，可以对复杂结构的倒塌过程进行模拟分析，完善和完善爆破工程方案和工艺。
Owing to its large underside and low barycenter,the hyperbolic cooling tower stood stable and was hard to demolish by blasting.Simulation of its collapsing process under blasting demolition with the use of dynamic finite element analysis program LS-DYNA was adopted in this paper,and showed a result of very close to the collapse of the real process.It proved that through proper selection of parameters and computing model the collapsing process of complex structure could be simulated and analyzed,and by which the blasting engineering program and technology could be improved and finished perfectly.
