Self-resetting prefabricated assembled pier
The invention belongs to the technical field of bridge engineering, and particularly relates to a self-resetting prefabricated assembled pier. The self-resetting prefabricated assembled pier comprises a foundation bearing platform section, a pier top section, a pier body, an energy consumption inner core, prestressed steel strands and SMA energy consumption ribs. The pier body comprises a top prefabricated section, a bottom prefabricated section and at least one middle prefabricated section which are vertically arranged, the bottom end of the energy dissipation inner core is inserted into the foundation platform section, and the top end of the energy dissipation inner core penetrates through the bottom prefabricated section and is inserted into the middle prefabricated section connected with the bottom prefabricated section; the prestressed steel strands comprise a plurality of overall prestressed steel strands and a plurality of local prestressed steel strands, the overall prestressed steel strands penetrate through the pier top section, the top prefabricated section, the middle prefabricated sections, the bottom prefabricated section and the foundation platform section at the same time, and the local prestressed steel strands penetrate through the energy dissipation inner core and the foundation platform section; the SMA energy dissipation ribs penetrate through the bottom prefabricated section and are anchored in the foundation platform section and the middle prefabricated section. The self-resetting function and the energy dissipation function of the prefabricated assembled pier can be considered at the same time.
本发明属于桥梁工程技术领域，尤其涉及一种自复位预制拼装桥墩。自复位预制拼装桥墩包括基础承台段、墩顶段、墩身、耗能内芯、预应力钢绞线和SMA耗能筋；墩身包括竖向布置的顶部预制节段、底部预制节段和至少一个中间预制节段，耗能内芯的底端插入至基础承台段内，顶端穿过底部预制节段插入至与其连接的中间预制节段内；预应力钢绞线包括多根整体预应力钢绞线和多根局部预应力钢绞线，整体预应力钢绞线同时穿过墩顶段、顶部预制节段、各中间预制节段、底部预制节段以及基础承台段，局部预应力钢绞线穿过耗能内芯和基础承台段；SMA耗能筋穿过底部预制节段并锚固在基础承台段和中间预制节段内。本发明能同时兼顾预制拼装桥墩的自复位功能和耗能功能。
