摘要
邯长线柔性墩加固时要求不能停车施工,大量柔性桥墩的加固改造及实施方案成为设计工作的重点和难点。通过对不加临时墩等辅助措施直接立模板施工桥墩的理论分析研究,确定了桥墩加固时需架设临时墩的施工步骤,以及临时墩设计、墩身加固、基础加固等措施。
Because the traffic of Handan-Changzhi Railway could not be interrupted when strengthening the flexible piers,the strengthening and renovation and implementation plans for a large number of flexible piers become to be the key points and difficult points in design.Firstly,the paper analyzes the construction with the formworks without the temporary piers.Afterwards,the construction procedure of pier strengthening which needs to erect the temporary piers is determined.Also,the temporary pier design,pier shaft strengthening,foundation strengthening and other measures are determined.
