Self-resetting prefabricated pier structure for single pile foundation and assembly method thereof
The invention discloses a self-resetting prefabricated pier structure for a single pile foundation and an assembly method thereof. The self-resetting prefabricated pier structure comprises a pile foundation, a prefabricated pile top platform, a prefabricated pier with a base and energy dissipation ribs. The pile foundation and the prefabricated pile top platform are assembled through connecting longitudinal bars; the prefabricated pier is arranged in a groove at the top of the pile top platform; the energy dissipation ribs are connected to the prefabricated pile top platform and a pier base. Aprefabrication technology is used for construction, the construction period is short, and environmental pollution is small. In addition, self-resetting is realized by utilizing the swinging of the pier on the pile top platform; earthquake energy of an input structure is dissipated through yield of the energy dissipation ribs, residual deformation of the bridge after an earthquake can be remarkably reduced or eliminated, normal use of the bridge after the earthquake is guaranteed, and the earthquake resistance of the bridge can be rapidly recovered by replacing the energy dissipation ribs, therefore the structure has wide applicability and positive social significance and scientific significance.
本发明公开了一种用于单桩基础的自复位预制装配式桥墩结构及其装配方法，包括桩基础、预制桩顶平台、带有底座的预制桥墩以及耗能筋；桩基础与预制桩顶平台利用连接纵筋组装；预制桥墩置于桩顶平台顶部的凹槽内；耗能筋连接预制桩顶平台与桥墩底座。本发明使用预制装配技术建造，施工周期短，环境污染小。此外本发明利用桥墩在桩顶平台上的摇摆实现自复位，利用耗能筋屈服耗散输入结构的地震能量，可以显著减小或消除桥梁的震后残余变形，保证震后桥梁的正常使用，并能通过更换耗能筋快速恢复桥梁抗震能力，具有广泛的适用性和积极的社会意义和科学意义。
