Along with the rapid development of social economy, a bridge serving as a transportation junction faces an increasingly serious threat, namely, the collision of a vehicle to a pier. Many domestic and foreign impact accidents show that when a large-sized vehicle is impacted, a pier designed according to the existing specification is likely to break and damage and cause the whole bridge to collapse, so that more serious secondary disasters are caused, and the serious consequences such as long-time sealing of the whole highway are caused. Therefore, the research on the problem that the vehicle collides with the pier has important practical significance.
At present, in the prior art, a simple static design method is adopted to perform anti-collision design on a pier, the influence of parameters such as the rigidity and the ductility of the pier on the collision force cannot be considered, and the difference from the actual situation is large. Secondly, the theoretical source of equivalent static forces in the specification is very vague. The general Specification for designing bridges and culverts (JTG D60-2004) in China directly indicates that the relevant regulations on the impact force of vehicles are obtained by referring to foreign specifications. In particular, the national standard still adopts a single, lower and unforced impact force design value at present, which is extremely unfavorable for the bridge safety in China. In addition, most of China currently adopts reinforced concrete anti-collision walls as main anti-collision devices, the reinforced concrete anti-collision walls are high in rigidity and weak in buffering capacity, although the piers can be protected from impact damage, the anti-impact force on automobiles is large, and the safety of personnel in the automobiles is seriously threatened.
