[Abstract]:With the continuous development of global economic integration and domestic construction, large projects such as energy, electricity and offshore platforms have been implemented, and the large transportation market in China is increasingly busy. As an important part of national construction, these large components can be quickly and safely transported to their destinations, not only for the whole nation. The development of the economy has a great influence, and has a very important strategic significance for the national large-scale engineering projects and national defense construction. In the transportation of such large components, the relevant enterprises need to put forward a reasonable and economical transportation scheme on the basis of scientific analysis of the feasible shipment. In this paper, we focus on the safety of large components in the process of water transportation. This paper takes the large bridge section of the deck barge as the research object, and studies the related technical problems involved in the process of shipment. Considering the large size of the transport bridge section, it is the first time in the history of domestic transportation. It is sent to the barge, and the loading scheme and fixing scheme of the bridge section are deeply studied. At the same time, the stability and strength of the barge under the state of the loading bridge are analyzed and studied, thus ensuring the safety in the course of navigation. The research has important practical value of Engineering and a definite theoretical guiding significance. The main research content of this paper is the main research content of this paper. Including: (1) research on the technical work involved in carrying on a large deck rolling ship, including the selection of the ship, the selection of tidal level, the fixing and leveling of the barge. The fact shows that the selection of suitable tidal level for rolling operation will greatly simplify the tilting load during the rolling process. Meanwhile, the rolling process will be divided into four stages. The concrete implementation method of tilting and stowage in rolling process is given. (2) the arrangement of the bridge section on the barge and the structure of the supporting frame are studied. On the basis of the analysis of the force situation of the bridge section in the transportation process, it is made out of the common method of the large structure. A set of reasonable and suitable system for the bridge section is used to check the safety of the system. (3) the stability of the barge under the loading bridge section is studied. The effect of the ship width, the free liquid on the stability of the ship is analyzed, and the relevant improvement measures are put forward according to the theory and practice. Static theory, the effect of bridge section moving on deck on the floatability and stability of barge was analyzed. The stability of barge under loading state was calculated and analyzed with Maxsurf software, and the stability calculation was checked with IMO specification. (4) in order to ensure that the hull strength met the requirements during the voyage, the whole ship was carried out on the barge. The rational boundary condition selection is very important for the calculation results. In this paper, the idea of inertia release is introduced in the process of dealing with the boundary conditions, and the stress situation of each component of the hull under various working conditions is calculated and analyzed.
