USE OF FLOATING (PONTOON) BRIDGES FOR THE ENGINEERING COVER OF TRANSPORT FACILITIES

Purpose. The purpose of this work is to investigate the topic of floating (pontoon) bridge systems as an option for overcoming water obstacles, a means of technical cover for national transport infrastructure facilities, and to analyze the current state of application of existing floating system property in order to determine the directions of further research in this area. Methodology. Research of existing floating (pontoon) bridge systems, their classification and technical characteristics, in the context of means of technical cover of important transport facilities and overcoming water obstacles in the conditions of modern warfare. Findings. Provision of temporary pontoon bridges is carried out during the creation of duplicate bridge crossings (ferry crossings) and the restoration of traffic in areas with destroyed transport facilities. Pontoons from sets of floating bridges can be used as platforms for installing special construction equipment during the construction (restoration) of transport facilities. A systemic analysis of floating (pontoon) bridges as an option for overcoming water obstacles for the technical cover of transport infrastructure facilities was conducted. All available floating (pontoon) means that can be used for their intended purpose were considered, and the need for modeling floating (pontoon) systems to expand their application possibilities was determined. Originality. The scientific interest lies in the fact that after conducting an analysis of the classification and technical characteristics of the available means of floating (pontoon) bridge systems, the main directions for further research and their simulations have been established, which will create conditions for their optimized application, taking into account the challenges of today in overcoming wide water obstacles, technical cover objects of the national transport infrastructure by laying duplicate temporary floating bridges (ferry crossings). Practical value. Pontoon systems for bridges are essential for providing technical cover for national transport infrastructure objects. Given the limited number of identical systems available for pontoon bridge systems, it is relevant to research the adaptation of different pontoon systems in one crossing, thereby expanding their application possibilities and providing all the necessary conditions for overcoming the widest water obstacles in Ukraine.
