摘要
以南阁大桥的主桥斜拉桥加固为工程背景,基于将挂梁与主跨相邻35m工字梁作为整体来计算桥梁结构损伤程度校验系数的研究现状,考虑将挂梁作为单独受力的简支梁置于两侧斜拉桥框架上来计算校验系数,并据此校验系数判定桥梁的损伤程度,对旧桥进行加固设计。
With the main bridge of Nange cable-stayed bridge in the background,hanging on the cross-beam and main-beam 35m adjacent to calculate the current situation as a whole bridge structure damage degree calibration coefficients,this paper consider the hanging beam as a separate force beams arranged at both sides of a cable-stayed bridge frame to calculate the coefficient,the degree of injury and this calibration coefficient to determine the bridge,and the old bridge reinforcement design.
