Modularized assembled bridge pier capable of being reset dynamically

LIU YINGQI / LI HANG / DU YUHANG / ZHANG XIEDONG

The invention relates to a modular assembly bridge pier capable of being dynamically reset. The modular assembly bridge pier comprises connecting beams, assembly modules, anchoring foundations, prestressed tendons, external filling blocks and prestressed tendon anchoring parts. Each assembly module comprises four bridge pier bodies which are mutually overlapped, connecting beams are arranged at the upper ends of the bridge pier bodies, anchoring foundations are arranged at the lower ends of the bridge pier bodies, two-way gentle slope contact interfaces with inwards-concave upper surfaces and outwards-convex lower surfaces are arranged between the adjacent assembly modules, and filling blocks are arranged outside the two-way gentle slope contact interfaces. Prestressed tendons are arranged in the assembly modules, and prestressed tendon anchoring parts are arranged on the prestressed tendons. According to the novel modular assembled bridge pier, large horizontal flexibility can be triggered in an epicenter to form a seismic mitigation and isolation system, residual slip-out displacement can be eliminated through earthquake peak-crossing energy before vibration is finished, the minimum use function is kept, the structural rigidity can be recovered through slight repair, and normal use can be continued.

本发明涉及一种可动态复位的模块化组装桥墩，包括连系梁、组装模块、供锚基础、预应力筋、外置填充块和预应力筋锚固件；所述组装模块包括四块相互叠加形成桥墩墩身，所述桥墩墩身上端设置连系梁，所述桥墩墩身下端设置供锚基础，相邻的所述组装模块之间设置具有内凹上表面与外凸下表面的双向缓坡接触界面，且外置填充块，所述组装模块内设置预应力筋，所述预应力筋上设置预应力筋锚固件。本发明既可以在震中触发较大水平柔度形成减隔震体系，又可以在震动结束前利用地震过峰能量消除残余滑出位移并保持最低限度使用功能，稍加修复便可恢复结构刚度并继续正常使用的新型模块化组装桥墩。
