摘　　要：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。In the light of the overpass characterized by more box structures, a demolishing scheme mainly applying hydraulic blasting was designed, and was optimized by numerical simula- tion. The result of engineering practice showed that by using hy- draulic blasting, the blasting cost of overpass demolition was low- ered effectively ,the duration of the project was shorten, and blas- ting harms such as blasting dust and so on were controlled suc- cessfully,so the blasting demolition of the overpass provided a reference for similar projects.
