摘要
肇庆市阅江大桥为三跨双塔单索面预应力混凝土斜拉桥。主要介绍其中跨合龙段的配重、顶推力施加等重要工序的施工方法。实践表明,采用配重、顶推施工方法,能确保中跨合龙段的混凝土施工质量,为后续工序的开展创造有利条件。
Zhaoqing Yuejiang Bridge is a threespan prestressed concrete cable-stayed bridge with single cable plane in twin towers. This papermainly introduces the construction methods to the key processes such as counter weight and jacking force. Practice shows that adopting counter weight& jacking force method can ensure the quality of concrete construction in mid-span closure section,and create favorable conditions for the subsequent operation.
