Method for reinforcing arch back enlarged section structure of old stone arch bridge
The invention discloses a method for reinforcing an arch back enlarged section structure of an old stone arch bridge, which comprises the following steps of: re-checking the bearing capacity of a foundation structure, removing an original bridge deck system and an on-arch filler newly-added base, backfilling on-arch filler again in the construction of an arch ring enlarged section, and the like. According to the method for reinforcing the arch back enlarged section structure of the old stone arch bridge, the cross section strength of the stone arch ring can be effectively improved, the designrequirement for load lifting is met, the original bridge appearance can be maintained, damage to an old stone arch ring is reduced, the construction work amount and difficulty are reduced, the manufacturing cost is saved, the construction period is shortened, stone arch bridge transformation can be conducted safely, efficiently and environmentally friendly, the green construction concept is met, and the old stone arch bridge transformation technology is enriched. Good reference significance is realized on similar engineering.
本发明公开了旧有石拱桥拱背增大截面结构的加固方法，包括以下步骤：基础结构承载力复核‑拆除原桥桥面系及拱上填料‑新增基座及拱圈增大截面的施工‑重新回填拱上填料等步骤，本发明的旧有石拱桥拱背增大截面的加固方法，既能有效提高石拱圈截面强度，满足提载的设计要求，又能维持原有桥梁外貌、减少对旧有石拱圈的破坏、减小施工工程量和难度、节约造价，缩短施工工期，使石拱桥改造能安全、高效、环保地进行，符合绿色建设理念，丰富了旧有石拱桥改造技术，对类似工程有较好的借鉴意义。
