摘要
确定自锚式悬索桥吊杆合理张拉力是自锚式悬索桥设计施工要解决的关键问题。基于吊杆在施工张拉过程中主缆位移具有弱相干性原理,将加劲梁视为连续梁结构,根据能量最小原理及变形协调原理,可确定吊杆的成桥张拉力。
Determining rational suspension cable force is a key problem to design and construct self-anehored suspension bridge. Utilizing the principle of weak coherence of main cable displacement, stiff girder is regarded as eontinuous beam. Rational suspension cable force of self-anchored suspension bridge can be determined according to least-energy principle and deformation compatibility principle.
