摘要(Abstract):
介绍了全长288m的钢筋混凝土双曲拱桥的爆破拆除。该桥相邻为一新建双曲拱桥,新建桥与拟拆除旧桥桥墩连为一体,要求拆除旧桥上部结构和墩(台)帽,另建上部结构。采用预拆除、对称破坏、同时解体的方案,爆破获得圆满成功。
This paper introduces a practical case of dismantling 288m in length reinforced concrete hyperbolic arch bridge by using controlled blastingThis bridge is adjacent to a newly built arch bridgeEach pier of the new and old bridges is adhere to each otherOnly the upper structure and pier platform of the old bridge are required to be dismantled by demolition and its piers and one bridge platform are needed to be kept for rebuildingThe blasting was successful by using beforehand demolition,symmetrical destruction,simultaneous disintegration
