摘要/Abstract

摘要： 应用重力刚度法推导了集中力和均布载荷作用下三塔四跨悬索桥主缆的无量纲位移的理论表达式；分析了跨数、边中跨比以及恒载和活载集度对三塔四跨悬索桥重力刚度挠度的影响规律，及三塔四跨悬索桥不同于两塔悬索桥的新特征。研究表明：多跨悬索在恒活载作用下主缆的力学特征主要决定了三塔四跨悬索桥整体结构刚度的基本特征，单跨悬索和多跨悬索力学行为的差异是两塔和三塔悬索桥力学特征差异产生的根本原因；应用重力刚度法分析的三塔悬索桥行为特征与基于有限元方法计算的结构行为特征有很好的一致性。

Abstract: The dimensionless deflection expressions of main cable for three-pylon-four-span suspension bridges under concentrated load and distributed load were derived by gravity stiffness method. Then the influence rule of the number of spans, the ratio of side span to main span, dead load and live load intensity on the gravity stiffness deflection of three-pylon-four-span suspension bridge was analyzed respectively. And the new characteristics of three-pylon-four-span suspension bridge which were distinguished from the conventional three-pylon-four-span suspension bridge were also analyzed. These conclusion indicates that the mechanical characteristics of the multi-span main cable under dead and live load determine the basic characteristics of structure stiffness of three-pylon-four-span suspension bridges; the different behavior between one-span cable and multi-span cable causes the difference of mechanical characteristics between two-pylon suspension bridges and three-pylon suspension bridges; and the behavior characteristics of three-pylon suspension bridges based on the gravity stiffness deflection method keeps well consistent with the behavior characteristics based on finite elements method on overall structure.

Key words: bridge engineering, the gravity stiffness method, displacement expressions, three-pylon-four-span, suspension bridges, deflection analysis
