Method and system for evaluating transportation and passage of large pieces of single-column-pier curved beam bridge

The invention relates to the technical field of safe passing of bridges, in particular to a single-column-pier curve beam bridge large-piece transportation passing evaluation method and system. According to bridge information and large transport vehicle information, preliminary assessment is performed on bridge space trafficability, bridge large transport simulation is performed on a bridge and a large transport vehicle based on a preliminary assessment result of the space trafficability, then a space trafficability assessment result of the bridge is obtained, and then a bridge finite element model is constructed according to the bridge information. Obtaining a structure trafficability evaluation result of the bridge based on the bridge finite element model; and finally, according to a space trafficability evaluation result and a structure trafficability evaluation result, obtaining a large-piece transportation passage evaluation result of the single-column-pier curve beam bridge, thereby realizing evaluation
