Steel-UHPC (Ultra High Performance Concrete) composite structure for splicing new and old T-beam bridges and construction method
The invention discloses a steel-UHPC (Ultra High Performance Concrete) composite structure for splicing a new T-beam bridge and an old T-beam bridge and a construction method. The steel-UHPC composite structure comprises a first splicing part arranged on the splicing width side of the old T-beam bridge and a second splicing part oppositely arranged at one end of a newly-built T-beam bridge, the first splicing part and the second splicing part are connected through a wet joint structure formed by combining a steel structure and ultra-high performance concrete (UHPC). The joint seam is combined with the UHPC through the steel structure to form a combined structure, the tensile property of the steel structure and the compression resistance advantage of the UHPC are fully played, the crack resistance of the joint seam is excellent, and the structural stability and durability are good.
本发明公开了一种用于拼接新旧T梁桥的钢‑UHPC组合结构及施工方法，包括设置在旧桥T梁拼宽侧的第一拼接部及相对设置在新建T梁一端的第二拼接部，所述第一拼接部和第二拼接部通过由钢结构与超高性能混凝土（UHPC）结合形成的湿接缝结构相连接。本发明拼接缝处通过钢结构与超高性能混凝土（UHPC）结合形成组合结构，充分发挥了钢结构的抗拉性能和超高性能混凝土抗压优势，拼接缝抗裂性能优越，结构稳定性和耐久性好。
