(54cl) Leakage Process of Refined Oil in Different Layered Soils

Pipeline transportation as the most important way of refined oil transport. As the refined oil is flammable、explosive and toxic. In the event of a leakage accident is easy to causing fire, explosion, poisoning and other accidents. If the accident occurred next to the inland river may cause serious impact to the water and its biological. This paper analyzed the leakage process of refined oil in different saturated soils of riverbed. Summarizes the diffusion mechanism and regular pattern of the refined oil in the soil of the river inland and the soil contact with the river. Combined with the leakage characteristics of the pipe hole leakage and its effect on the process of leakage diffusion. The two-dimensional sand box model experiment has established to Analysis and conclusions of the corresponding leakage diffusion.
