The results of numerical analysis of the decomposing process of a single pneumatic cassette pontoon bridge as a temporary roadway are presented in the paper. The cassette pontoon bridge is an innovative solution designed for quick assembly of the construction on water. The repeatability of a single module, facility of transportation and operation mean that it can be used in many applications: crossings for military vehicles (e.g. tanks or wheeled vehicles lightarmoured), replacement crossing for trucks (e.g. delivering materials for the construction of the permanent bridge), ribbons replacing flooded roads and footbridges on suddenly increased watercourses. The main problem in our consideration is single cassette pontoon stability at the moment of filling the pontoon. The numerical investigations presented in the present paper aimed at testing the influence of the load on the process of filling the single cassette pontoon. To perform the analyses, LS-DYNA software, in which the dynamic equations of motion are solved using an explicit time integration method, was used. The paper presents initial verification of the initial conditions influence on the process of filling the single cassette pontoon. An important factor considered in the work is a strong influence of an unbalanced load distribution on the surface of the cassette capacity on the process of filling the pontoon.
