城市中心公路立交桥的拆除一般都采用控制爆破,针对立交桥箱形结构较多的特点,提出水压爆破为主的拆除爆破方案,并通过计算机模拟优化,工程实践结果表明,水压爆破拆除有效降低了爆破成本,缩短了工期,成功控制了爆破粉尘等危害,值得此类工程实践借鉴参考。 The demolition of urban highway overpass usually adopts controlled blasting. According to the characteristics of overpass box-shaped structure, the disassembly and blasting scheme based on hydraulic blasting is proposed and optimized by computer simulation. The engineering practice shows that the hydraulic blasting demolition is effectively reduced Blasting costs, shorten the construction period, the successful control of the blasting dust and other hazards, it is worth drawing reference for such projects.
