In order to ensure a safe and comfortable rail transportation, the manufacture of the line bearing must be constructed in such a way that it does not lead to sitting and undulations. In particular, different structures can be formed in the transition to the ground with art structures. These settlements can cause problems in terms of comfort and navigation. In this study, the transition between the art structures and the fillings were evaluated. For this purpose, the most commonly used German and French models were used. Behavior of approach filling models according to rock, sand and clay units at the bottom were investigated by numerical method. For this purpose, according to the filler load of 9 meters from a certain distance from the structure of art structure using the finite element method (FEM) was made by using the computer program Plaxis 2D V. 8.2. According to the results of the analysis, it is concluded that the floors under the fillings are more important than the fill type, whereas the approach type is not very important in the rigid environments, whereas in the plasticized environments, the German approach filler type has a relatively higher performance than the French fill type.
