| 摘 要： | 介绍了一座 6 0 4m的超长大桥的控制爆破拆除。确定爆破方案时 ,采用了先破坏T形梁、再爆破桥墩、最后用外敷药包进行二次破碎的新设计思想。可检测的非电起爆系统的应用 ,使大桥的爆破拆除安全、可靠、快速、经济 ,为类似工程提供了可选择的新技术。

| Abstract: | In this paper, demolition of an ultralong bridge with a length of 604m by controlled blasting was introduced. A new design thought of that T shape beams were destroyed firstly, abutments blasted secondly and secondary crushing with unconfined charges was finally carried out was adopted during determination of blasting scheme. The application of a detectable non electric initiation system makes the blasting demolition of the bridge safe, reliable, quick and economic, providing a new alternative technology for other similar projects. |
