【摘要】 探讨悬索桥恒载作用下缆索线形及其内力的计算方法。先用悬链线公式给出主缆的近似位置,然后通过对结构进行拆分、组合的分析过程,给出缆索成桥线形及其内力的计算步骤。对润扬大桥悬索桥的成桥状态进行分析,并与竣工实测数据进行对比。结果表明,该方法可以获得较准确的计算结果。更多还原

【Abstract】 An algorithm for geometric shape and internal force of the cables of suspension bridge under dead load is studied.The probable locations of the main cables of the bridge are firstly given by centenary formula and the calculation steps for the geometric shape as well as the internal force of the cables of the completed bridge are provided through analysis process of disconnecting and assembling of the structure.The completed suspension bridge of Runyang Bridge is then taken as an example and analyzed by the algorithm,and the results of the analysis are compared with the field measurement data collected at the completion stage.It is shown that the algorithm presented in the paper can obtain fairly precise calculation results.更多还原
