The object of the paper is experimental and numerical verification of a pontoon bridge prototype section. The main part of a single segment is a waterproof cassette which contains a shell (pontoon). After filling with the air, the pontoon assures the required buoyancy. The cassette, in which the shell is located, has a movable bottom. Pontoon bridges are built of ready-to-use repeatable segments and they may be used as temporary crossings. Verification of the bridge modules was performed by launching a demonstrator compound of two modules of the pontoon bridge section, filling the pontoons with air and measuring their immersion. The test was performed in the pool, in the Military Engineering Works. S.A. (WZInż. S.A.) in Deblin. Recording and measurements were performed with two Phantom V12 cameras placed on static tripods. It allowed reading from each of the cameras the heights of the midpoints of the prow and the starboard above the water surface, and the inclination angle of the pontoon unit in transverse and longitudinal planes. The combination of these results allowed calculation of height of the roadway centre of pontoons set above the water surface. Displacement and stability of the structure was specified based on analytical calculations. This paper presents the results of numerical calculations of launching a pontoon bridge section demonstrator. Correctness of the numerical methods of calculation was examined based on a comparison of numerical and experimental results.
