摘要
介绍了一座复杂环境下砖混结构烟囱的爆破拆除。通过选取合理的爆破切口形式、孔网参数,并对烟囱爆破过程中的振动及塌落振动进行了校核,采取了有效的安全防护措施,使得烟囱按照预定的方式倒塌,爆破取得了成功,可以为类似复杂环境下烟囱的爆破拆除提供参考和借鉴。
blasting demolition of a brick concrete chimney in a complicated environment is introduced. By selecting the reasonable form of blasting cut, pore network parameters and the vibration and ground of chimney blasting vibration in the course of the check, take reasonable security protective measures, the chimney collapsed in a predetermined manner, blasting success for similar complex chimney environment and provides reference for demolition.
