摘要
通过采取非常规的布孔方式、药量控制、起爆顺序 ,实施严密防护措施 ,在城市交通要道上及电、水、通信管线密集且有邻近桥梁的情况下 ,对坚固石拱桥成功实施控制爆破拆除。
The unconventional blasting hole arrangement, explosive charge coated and blasting sequence were adopted for the safety purpose. Under conditions of electrical wires, water pipes, communication cable and a bridge and adjacent, a controlled blasting for the solid stone arch bridge has been successfully performed.
