Modular pontoon bridge: an ad hoc supplement to transport infrastructure

This paper presents a new concept of a modular pontoon bridge designed to provide a temporary crossing over a water obstacle. The operating principle of a repeatable module of such a bridge is described. A pneumatic pontoon, the load-bearing element of the structure, is filled with air, which allows its buoyancy to be regulated. The results of numerical simulations of the behavior of the modular pontoon bridge in various configurations, conducted using the Ls-Dyna software, are presented. The non-linear dynamic analyses performed allowed for the determination of the displacement values of the bridge deck.Logistics, as a process of planning, implementing, and controlling the efficient and effective flow of goods, must take into account existing road infrastructure.
In the planning process, unforeseen circumstances must be anticipated, such as natural disasters or local restrictions resulting from, among other things, the temporary closure of transport routes. During a comprehensive analysis of a project, it is also worth considering the existence of solutions that enable the technical security of the supply chain. Such a solution could be a modular pontoon bridge with adjustable load capacity. (…)
