Road Temporary Collapsible Bridges

Abstract

Abstract. Problem. Bridge crossings on motorways are the most vulnerable facilities. Restoration of bridges destroyed as a result of accidents, natural disasters and military operations is crucial for the functioning of Ukraine's economy and armed forces. The organisation of bridge reconstruction works on motorways remains one of the most challenging tasks. Reconstruction of bridges involves significant expenditure of effort, money and time. The main requirement is to restore destroyed bridges in a short time. The use of sets of temporary collapsible road bridges allows for the restoration of interrupted traffic across water obstacles in a short time. Goal. The goal of the research is to generalise and systematise temporary collapsible bridges of various static systems for civil and military purposes used in Ukraine and around the world. Methodology Methods of analysis and generalisation are used to systematise road temporary collapsible bridges of various static systems for civil and military purposes used in different countries. Results. The data for the use of temporary road collapsible bridges in Ukraine were obtained. The main characteristics of temporary bridges are: the size of spans, bridge length, carriageway width, load capacity, weight of bridge structures, main bridge elements, assembly time, etc. Originality. He article presents the results of generalisation and systematisation of temporary collapsible bridges of various static systems for civil and military purposes used in Ukraine and around the world. Practical value. The objective of the study was to familiarise a wide range of bridge specialists with the peculiarities of using various designs of temporary collapsible bridges and further modelling of organisational and technical solutions for their use in the context of military aggression against Ukraine.
