Supporting structure for reconstructing self-anchored suspension bridge and bridge reconstruction method
The invention discloses a supporting structure for reconstructing a self-anchored suspension bridge and a bridge reconstruction method. The newly-built bridge comprises independent continuous beam bridges arranged on the two sides of a to-be-dismantled old bridge and a middle bridge amplitude structure for connecting the two independent continuous beam bridges after the to-be-dismantled old bridge is dismantled. The supporting structure comprises a temporary supporting device needing to be dismantled after reconstruction is completed, and a permanent supporting device serving as a part of a newly-built bridge after reconstruction is completed. The permanent supporting device comprises a plurality of permanent supports and a cross beam supporting system; the temporary supporting device comprises a plurality of temporary supports and corresponding temporary piers. During reconstruction, two independent continuous beam bridges are firstly constructed, then traffic is guided to the independent continuous beam bridge on one side, and the independent continuous beam bridge on the other side serves as a construction channel; and after the middle bridge amplitude structure is installed, the suspenders are tensioned in batches to complete system conversion of the newly-built bridge. On the premise that the traffic requirement is met, the bridge construction project can be smoothly carried out.
本发明公开了用于改建自锚式悬索桥的支撑结构及桥梁改建方法；新建桥梁包括设置在待拆除的老桥两侧的独立连续梁桥，以及在待拆除的老桥拆除后，连接两幅独立连续梁桥的中间桥幅结构；支撑结构包括改建完成后，需要拆除的临时支撑装置，以及改建完成后，作为新建桥梁的部件的永久支撑装置；永久支撑装置包括多个永久支座，以及横梁支撑系统；临时支撑装置包括多个临时支座，以及相应的临时墩。改建时，先建造两座独立连续梁桥，然后，将交通导改至一侧的独立连续梁桥，另一侧的独立连续梁桥作为施工通道；完成安装中间桥幅结构后，分批次张拉吊杆完成新建桥梁的体系转换。本发明在保证满足保交通需求的前提下，能够顺利地开展桥梁建造工程。
