Assessing the effectiveness of restoring bridge structures with accelerated resumption of traffic
Аннотация
The technical condition of bridge structures (bridges, overpasses and others) on highways has been the subject of research for a large number of works in recent years. This technical condition changes over a long time, and in some cases (emergencies, military operations, sudden failures) – very quickly. In such situations, accelerated restoration of traffic on these transport facilities is required. Often, bypassing these bridges is impossible or difficult for a number of reasons: economic, time, social, technical and others. The classical methods of restoring objects (the construction of a new structure or the reconstruction of an existing bridge) are very long in time and laborious or technically complicated. In such cases, solutions are needed to restore damaged bridge structures in accelerated formats. The choice of a specific method should be made according to the appropriate methodology for assessing efficiency, taking into account, first of all, the recovery time, the availability of resources and capabilities, the cost, as well as a number of other points.This article presents this method, based on the analysis of existing recovery methods, and draws the appropriate conclusions. During the development of the method, performance criteria (indicators) and their interval and mean values were adequately substantiated and proposed. In addition to the proposed methodology for assessing efficiency, the results of the work resulted in conclusions made on it about the most appropriate ways to restore bridge structures with an accelerated resumption of traffic on them. The scope of the study results may be solutions for emergency situations at transport facilities.
