| 摘 要： | 介绍了用定向爆破拆除复杂环境下结构体破损的砖烟囱.为防止烟囱在爆破时发生后座和散架,确保烟囱在倒塌过程中不发生偏移,根据烟囱的周围环境和结构特点,选择了合理的爆破切口长度,对破损的支撑体部分采取了加固措施,对爆破切口采用对称微差爆破,取得了良好的爆破效果.

| Abstract: | The damaged brick chimney under complex environment was introduced by directional explosive demolition.To prevent the backward or fall apart when blasting and to ensure not deflection in the collapse process,the rational blast cut length,the reinforcement measure of broken support part and the symmetrical delay time firing of blast cut were chosen to obtain the good blasting results according to the chimney's structural characteristics and the surrounding environment. |
