Single-pier bridge anti-overturning structure and construction method thereof
The invention relates to a single-pier bridge anti-overturning structure which comprises a first structural part and a second structural part which are arranged on a bridge pier, the first structuralpart and the second structural part surround the bridge pier, and the first structural part and the second structural part are fixedly connected through a connecting part. The upper end face of the first structural part and the upper end face of the second structural part are each additionally provided with a supporting point, namely the first supporting point and the second supporting point, andheight-adjustable supports are arranged at the supporting points. According to the structure, the anti-overturning performance of a single-pier bridge is improved, meanwhile, an original structural system of the bridge is not changed, original distribution and local stress of dead load are not changed, basic load is basically not increased, and it is guaranteed that a newly-added fulcrum is not disengaged and durable in the long-term use process.
本发明涉及一种独柱墩桥梁抗倾覆结构，包括设置在桥梁桥墩上的第一结构件和第二结构件，所述第一结构件和第二结构件环抱所述桥梁桥墩，所述第一结构件和第二结构件通过连接件固定连接；所述第一结构件和第二结构件的上端面均新增设置一个支点，分别为第一支点和第二支点，并在支点处设施可调高支座；该结构在提高独柱墩桥梁抗倾覆性能的同时，不改变桥梁原有结构体系，不改变恒载的原有分配和局部受力，基本不增加基础负荷，保障新增支点长期使用过程中不脱空、耐久性。
