通过对烟囱倒塌过程的受力状态和运动规律的分析，对烟囱倒塌过程进行数值求解，得出在不同时刻烟囱的倾倒角度及烟囱的倾倒位置，利用这些数据可以重现烟囱的爆破过程；优化烟囱的爆破设计方案及确定折叠式定向倾倒的延发时间。
By analyzing the stress state and movement law of the chimney collapse process, the chimney collapse process is numerically solved, the dumping angle of the chimney and the dumping position of the chimney at different times are obtained, and the blasting process of the chimney can be reproduced by using these data; Blasting design of the chimney and determining the extension time of the folded orientation dump.
