摘　　要：随着城市交通的快速发展,原有交通道路无法满足现有交通流量,城市道路改建工程也越来越多。本文结合胜利黄河大桥维修改造工程建设中装配式预应力混凝土桥梁的拆除实例,介绍桥梁分部位拆除、吊离、破碎的施工工艺。该工艺施工快捷,安全可靠、环保,为以后我国类似城市桥梁的拆除提供了一定的参考价值。With the rapid development of urban transportation,the existing transportation roads cannot meet the existing traffic flow,and there are more and more urban road reconstruction projects.This article combines the demolition example of prefabricated prestressed concrete bridges in the maintenance and renovation project of the Shengli Yellow River Bridge to introduce the construction process of bridge partial demolition,lifting,and crushing.This process is fast,safe,reliable,and environmentally friendly,providing a certain reference value for the demolition of similar urban bridges in China in the future.
