南水北调丹江口汉江大桥设计是一座横跨汉江的特大桥,本文阐述了多跨长联三向预应力混凝土连续梁的结构设计特色、设计及施工中新技术的运用,着重介绍了主桥箱梁结构的设计与计算及大跨度桥梁在施工过程中受力与变形的监测和控制的运用,同时介绍了直螺纹套筒技术在灌注桩钢筋连接中的应用、弹性减震球型钢支座在工程中的应用。对今后多跨混凝土连续梁桥的设计具有一定的参考价值。
Design of South-to-North Water Diversion Hanjiang River Bridge in Danjiangkou is a special bridge spanning the Han River. This paper describes the structural design features, design and application of new technologies in the construction of three-direction prestressed concrete continuous beams with multi-span, and emphatically introduces the structure of the main bridge box girder The design and calculation of long-span bridges and the application of force and deformation monitoring and control during the construction process are introduced. Meanwhile, the application of straight-thread sleeve technology in the connection of bored pile reinforcement is introduced. The application of elastic damping ball bearing in engineering Applications. It is of certain reference value to the design of multi-span concrete continuous beam bridge in the future.
