摘要(Abstract):

基于桁架拱桥成功爆破拆除的工程实践,本文总结了拆除爆破桁架拱桥工程的方法。主要阐述了桁架拱桥控制爆破的方案设计与施工、延时起爆网路、安全防护及爆破效果,并对不完善之处提出了改进方案。其爆破经验为类似爆破工程提供借鉴和参考。
Based on the engineering practice of controlled blasting demolition of truss arch bridge,this paper summarized the method of this project and mainly discussed its blasting program and construction,detonation delay network,safety protection and blasting results.Also put forward how to make some improvements,which could provide some experience for the similar engineering.
