摘要
为了解决复杂城市环境下岩石边坡控制爆破的有害效应问题,依托某景区岩石边坡爆破工程,提出相应的爆破设计方案。方案采用以弱松动定向控制爆破为主,辅以浅孔城市爆破以及预裂爆破的爆破设计,提出了各爆破形式的爆破设计参数,设计了相应的起爆网络、起爆顺序及装药结构。通过严格执行该方案,大大降低了爆破振害,实际爆破施工效果达到预期目标。该设计可为其他复杂城市环境爆破工程提供参考。
Based on a rock slope blasting project in a scenic spot,a relevant blasting design scheme is proposed for solving the harmful effects caused by controlled blasting of rock slope in complex urban environment. Weak loose directional controlled blasting was combined with shallow-hole urban blasting and pre-splitting blasting in this scheme. The blasting design parameters of each design are presented with corresponding detonating circuit and sequence as well as charge structure.Through the strict implementation of this scheme,the vibration damage by blasting is greatly reduced and the actual blasting construction effects meet the desired objectives. This design can be reference for similar projects.
