摘要:
以沈阳铬渣无害化处理厂解毒房爆破拆除为工程实例，研究内含解毒塔的不对称框架结构的解毒房的定向拆除爆破。根据实际工程设计模拟方案，针对不同爆高和不同延期时间，采用LS-DYNA软件进行4种爆破方案的模拟，经对比分析,得出最佳的爆破方案。分析解毒塔下落过程可知，最后一排立柱起爆的时间要小于整体形成有效倾角的时间，同时也要小于解毒塔的落地时间，起爆时间与爆高是解毒房顺利倒塌的关键。理论计算解毒房倒塌转角随时间的变化,与模拟较为符合;实际倒塌转角随时间的变化与模拟过程更为接近，采用LS-DYNA软件可以较好地模拟爆破拆除过程。
Abstract:
Blasting demolition project for a detoxification house in Shenyang Chromium Residue Harmless Treatment Plant was used as an example to study directional demolition blasting of a detoxification house with a symmetric frame structure. Simulation programs were designed according to the actual engineering. Software LS-DYNA was used to simulate four blasting schemes with different blasting heights and different delay times, and the optimum blasting scheme was obtained by comparison and analysis. Analysis of the where abouts process of the detoxification house shows that the initiation time of the last row column is less than the time of effective rake angle of overall, and also less than landing time of detoxification house. Initiation time or blasting height is the key to achieve successful collapse of the detoxification house. Theoretical calculation of collapse angle change of the detoxification house is in accordance with the simulation, and the variation of the actual collapse angle with time is much closer to the simulation process. Using LS-DYNA can better simulate blasting demolition.
