UHPC board and concrete combined type frame slab bridge and construction method thereof
The invention discloses a UHPC (Ultra High Performance Concrete) board and concrete combined type frame slab bridge and a construction method thereof, the structure part of the UHPC board and concrete combined type frame slab bridge comprises a plurality of groups of bridge piers arranged at equal intervals, cover beams are arranged on the bridge piers, UHPC board trusses are erected among the cover beams, concrete is poured on the UHPC board trusses, and the UHPC board trusses are connected with the cover beams through the concrete. The ends of the adjacent UHPC plate trusses are correspondingly provided with hogging moment area UHPC prefabricated slabs, and the two ends of each hogging moment area UHPC prefabricated slab are connected with concrete at the ends of the UHPC plate trusses on the two sides respectively. Compared with a cast-in-place common concrete structure, the UHPC board concrete combined continuous frame slab bridge designed by the invention is better in stress performance, better in durability, more convenient in construction process and lower in construction cost, has very remarkable advantages, and has relatively high applicability to construction of bridges in coastal splash zones.
本发明公开一种UHPC板与混凝土组合式框架板桥及其施工方法，其结构部分包括多组等间距设置的桥墩，所述桥墩上设有盖梁，所述盖梁之间均搭设有UHPC板桁，所述UHPC板桁上浇筑有混凝土并利用混凝土与盖梁连接，相邻所述UHPC板桁的端部对应设有负弯矩区UHPC预制板，所述负弯矩区UHPC预制板两端分别与两侧的UHPC板桁端部的混凝土连接。本发明设计的UHPC板混凝土组合式连续框架板桥相比现浇普通混凝土结构受力性能更优、耐久性更好、施工工艺更便捷，施工成本更低，具有十分显著的优势，对于沿海浪溅区桥梁的建设具有较强适用性。
