Self-adaptive variable stiffness structure of road and bridge transition section
The invention belongs to the field of road and bridge transition section equipment, and particularly relates to a road and bridge transition section self-adaptive variable stiffness structure. The self-adaptive variable stiffness structure comprises a plurality of raft-shaped foundations and a plurality of self-adaptive variable stiffness structures, wherein the raft-shaped foundations are arranged on an unstable foundation; wherein the raft-shaped foundation is a reinforced concrete box, a through box, a composite I-shaped frame or a ship body; the plurality of supporting columns are arranged on the raft-shaped foundation; the top cover plate is fixed on the plurality of supporting columns; wherein a road surface unit is laid on the top cover plate, and a rigid butt strap on the top cover plate is in lap joint with a bridge body unit; wherein the self-adaptive variable stiffness structure space is filled with roadbed filler. The road and bridge transition section self-adaptive variable stiffness structure is simple in appearance, reasonable in structural stress and rapid and convenient to construct, roadbed settlement in the direction away from a bridge site is gradually changed, damage to the road and bridge transition section is reduced, smooth and safe passing of vehicles is guaranteed, and the road and bridge transition section self-adaptive variable stiffness structure has wide prospects of large-scale construction and application.
本发明属于路桥过渡段设备领域，具体为一种路桥过渡段自适应变刚度结构。所述自适应变刚度结构包括：筏形基础，若干所述筏形基础置于不稳定地基上；其中筏形基础为钢混箱、通箱、复合工字架或船体；以及支柱，若干所述支柱设置于筏形基础上；顶盖板，所述顶盖板固定于若干所述支柱上；其中，所述顶盖板上铺设路面单元，所述顶盖板上的刚性搭板与桥体单元搭接；其中自适应变刚度结构空间内填充路基填料。该路桥过渡段自适应变刚度结构外观简洁，结构受力合理，施工快速便捷，使沿远离桥位方向路基沉降的逐步变化，减小了路桥过渡段的病害，保证了车辆的平顺、安全通行，具备规模化建设应用的广阔前景。
