| 摘 要： | 在分析附加内力对劣化拱轴线大跨度石拱桥内力影响的基础上,运用影响线加载法对拱上建筑进行分节段分步骤调整,通过Midas/Civil结构软件对调载工序进行验证,提出劣化拱轴线大跨度石拱桥拱上建筑合理调载工序。工程实践应用表明,所提出的劣化拱轴线大跨石拱桥拱上建筑调载工序是合理的、可行的。

| Abstract: | Basing on the analysis of additional internal forces influencing the long-span stone arch bridge with deteriorated arch axis,spandrel construction is adjusted in steps and segments by the influence line loading method. The adjusting load process is verified by Midas/Civil structure software,and the reasonable adjusting load process of spandrel construction for long-span stone arch bridge with deteriorated arch axis is proposed. In light of engineering practice,it is showed that the adjusting load process pr... |
