Rapid structural safety evaluation system of expressway bridges under bulk transportation

Abstract

In view of the increasing of heavy industrial equipment transportation on highway and the practical needs of the bridge safety assessment and consultation of heavy transportation, main characteristics of heavy transportation are firstly summarized. Then, the safety assessment criteria and rapid assessment method of the bridge structure regarding passage of large vehicles are studied and demonstrated via specific project examples. Finally, based on the proposed bridge structure safety assessment criteria and rapid assessment method, the bridge structure model library collected from main passages of highways is established. In addition, based on cloud service, the model library is integrated into a rapid safety assessment system of heavy-cargo transportation over bridge structures for realizing the informationization of safety assessment of bridges with heavy transportation, greatly shorten the approval procedure of highway heavy-cargo transportation, and facilitate the construction of major projects such as energy and equipment manufacturing.
