Structure and method for compositely reinforcing old bridge plate
The invention discloses a structure and a method for compositely reinforcing an old bridge plate. An active reinforcing structure for improving the bending resistance and the bearing capacity of a beam body and reducing or delaying the development of transverse cracks at the bottom of the beam is arranged on the bottom surface of the beam plate between two supporting piers; the passive reinforcing structures are arranged at webs on the two sides of the beam plate and used for improving the shear capacity of the webs and limiting and restraining continuous development of vertical and oblique cracks of the webs. The mode of combining active reinforcement and passive reinforcement is adopted, so that the shear bearing capacity of the beam body is enhanced, the tensile stress of the beam body is improved, the time of cracking of the bottom plate is delayed, and generation and development of cracks of the web are limited.
本发明公开了一种对旧桥梁板进行复合加固的结构及方法，本发明在两支撑桥墩之间的梁板底面上设有以提高梁体的抗弯和承载能力、减少或延缓梁底横向裂缝发展的主动加固结构；和在梁板两侧腹板处设有以提高腹板抗剪能力、限制约束腹板竖向、斜向裂缝继续发展的被动加固结构。本发明采用主动加固与被动加固相结合的方式，以增强梁体的抗剪承载力，提高梁体的拉应力，延缓底板出现裂缝的时间，限制腹板裂缝的产生和发展。
