Two-way curved arch bridge dismantling construction method
The invention discloses a two-way curved arch bridge dismantling construction method. The method comprises the following steps that S1, a bridge deck system is dismantled; s2, partition numbering is carried out, and arch structures are symmetrically dismantled S3, erecting a cable system; s4, the arch rings are symmetrically dismantled through partition numbering; s5, the cable system is dismantled; according to the construction method, vertical layering, transverse striping and longitudinal segmentation are provided by combining the structural characteristics and stress characteristics of the two-way curved arch bridge; according to the bridge dismantling thought of symmetrically dismantling from the middle of the bridge to the bridge abutment in the longitudinal bridge direction and from the two sides to the middle in the transverse bridge direction, gradually and uniformly reducing load and balancing stress, the construction method guarantees the safety of the bridge dismantling construction process, meanwhile, a traditional support and a construction trestle do not need to be built, engineering investment is reduced, the requirement for the construction environment is low, and applicability is high.
本发明公开了一种双曲拱桥拆除施工方法，包括以下步骤:S1：拆除桥面系；S2：分区编号对称拆除拱上结构；S3：架设缆绳系统；S4：分区编号对称拆除拱圈；S5：拆除缆绳系统；S6：分段拆除桥墩及桥台，本发明结合了双曲拱桥结构特征及受力特点，提出竖分层、横向分条、纵向分段；纵桥向从桥中间至桥台，横桥向从两边向中间，对称拆除，逐步均匀减载，平衡受力的拆桥思路，该施工方法在保证拆桥施工过程安全性的同时无需搭传统支架、施工栈桥，减少了工程投入，对施工环境要求低、适用性强。
