针对京九线下行茨园特大桥线梁偏心超限问题,提出采用拨道方法进行整治,对两条曲线分别提出了两种设计方案,经过比选得到最优方案。此外,还从导致线梁偏心超限的原因出发,介绍了线桥养护维修注意事项,提出建立线桥养护维修协调机制,从而有效减少线梁偏心超限问题。 In view of the over-limit of the beam of Beijing-Kowloon Line Tiyuan Park Super-Large Bridge, this paper proposes to use the track alignment method to rectify. Two design schemes are proposed respectively for the two curves, and the optimal scheme is obtained through comparison and selection. In addition, starting from the cause of over-limit of the line beam, this paper introduces the attention of the line bridge maintenance and repair, and proposes to establish the coordination mechanism of the line bridge maintenance and repair so as to effectively reduce the over-limit of the line beam.
