摘要
该文基于悬链线计算分析理论,将自锚式悬索桥空缆状态,简化为受沿弧长均布的自重荷载与吊索处集中力作用的柔性索,对成都市清水河自锚式悬索桥主缆的无应力长度进行了计算分析。可为类似的桥梁设计和施工提供参考。
Based on the catenary calculation analysis theory, the article simplifies the open cable state of self-anchored suspension bridge into the flexible cable born by the deadweight load equally distributed along the arc length and the force action centralized at the suspended cable, and calculates and analyzes the un-stressing length of the main cable for the self-anchored suspension bridge of Clearing Water River in Chengdu City, which can be referred for the design and construction of the similar bridges.
