Most of Domestic railroads was composed of the ballast track that had an advantage of LCC (Life Cycle Cost) and it was constantly developed with the railroad materials such as a fastening components. Recently, it also has turning point to the concrete slab tracks that improve the driving stability. As the concrete tracks are planned, the Rail Level is regarded as an important factor on the construction expense. Although the Rail Level becomes lower than before that is to be stable enough for vehicle operating with technological development. Because of the B2S features that used a precast panel, estimation of its optimum thickness is also important factor for not only expense but also efficiency during mortar construction to the bottom layer of panel. This paper presents to calculate the optimum thickness of B2S panel according to various axle loads and rail support stiffness, and to evaluate the applicability. It also analyzes the effect from train loads to track by the 3D model, when the various rail support stiffness is applied for axle loads such as subway, light rail transit, railroad for convention line.
As a result, it was evaluated that applicability of B2S slab track related to the conclusion for 2 types of railroads of other operating condition. And it should be used for the improvement of existing and construction railroads and tried to secure the basic data for structural safety and optimal track design.
