This utility model discloses a fracture-resistant bolt connection pair structure for long-span steel bridges, including a bolt body, an anti-loosening nut assembly, an anti-corrosion washer assembly, a first steel bridge connection plate, and a second steel bridge connection plate. This utility model relates to the field of steel bridge connection structure technology. This fracture-resistant bolt connection pair structure for long-span steel bridges forms a dual stress dispersion structure through a tapered connector between the bolt head and the bolt segment, and four U-shaped stress relief grooves on the bolt segment. This significantly reduces the stress concentration coefficient at the bolt connection, preventing fatigue crack initiation under long-term alternating loads. Simultaneously, the main nut and auxiliary nut, in conjunction with an annular boss, compress the nitrile rubber elastic bushing, continuously compensating for preload attenuation caused by vibration, achieving a preload retention rate of over 90%. This solves the problem of uneven bolt stress caused by loosening of traditional nuts. It ensures the fracture-resistant performance of the bolt connection pair from both "fatigue resistance" and "loosening prevention" dimensions, meeting the core stress requirements of long-span steel bridges.
