摘要
介绍了(30+10)万吨级船坞围堰的爆破拆除技术。该围堰长约170m,自身结构复杂,周边环境复杂,施工难度很大,被认定为A级拆除爆破工程。该爆破从设定安全控制标准入手,进行爆破方案的选择和爆破参数设计,然后进行安全防护设计。文中介绍了爆破器材检验、爆破试验和振动、位移及水击波检测情况,并对爆破效果进行了分析。该工程对类似工程很有参考价值。
The paper discussed the demolition blasting technology of boatyard cofferdam of（30 ＋ 10） × 10^4 tons. Having a length of 170m, with complex structure and located in complicated surroundings, the cofferdam＇s demolition was very difficult,and therefore, was regarded as A grade demolition blasting engineering in terms of the difficulty in its operation. Started from enactment of safety standard, the selection of blasting scheme, the design of blasting parameter and safety defensing were carried out. The present paper introduced the inspection of blasting materials, the blasting experiment, the measurements of blasting vibration, displacement and the resulting water wave. The blasting effect was also analyzed. The blasting technology is of reference value to the similar engineering.
