Samenvatting

The Resilient Delta research group has been researching in infrastructures stability under a case study of ‘flooding of the territory of the Reimerswaal municipality.' For this, this research is carried out by the research group to check the effect of the flood on the railway. This research had aimed to check the erosion resistance and the bearing capacity of the railway trajectory during and after the flood. For that, the flood scenarios on VNK2 (the Dutch safety map 2) has been used to check this railway.
The railway trajectory stability had been tested by applying different instruments such as desk research of the previous studies, a modeling program (D-Geo Stability Program) and geotechnical calculations. Furthermore, with this project technical and functional requirements of the railway structure had been set up. These requirements were used when the railway was checked.
Further, the Multi-Criteria Analysis had been applied to this research. The main idea of the MCA on this project is to come up with three designs to include the ballast and water currents on calculations of the railway test. After revelations, the ballast considered as revetments and considered as a load on the dike structure. In additions, the current as well has taken into accounts during this research.
The results of this report have been determined by the primary methods to check the slope stability, settlements, and currents. Slope safety factor checks have been done using D-Geo stability model.
The results show that location one and two have a low safety factor (lower than 1.3). In both locations, the slope losing its stability during the flood when a train load is a presence. Also, location three has high slope stability and its slop still stable during the flood. Not only, the slope stability but also the slope grass revetment does not satisfy during checks. As for the three locations the grass has the different type of grass with big trees on the slope.
Furthermore, with settlements checks location three gets the highest settlements value during and after the flood. The research has concluded that the railway is eroded during present of water.
However, the soil properties of the embankments had been based on a historical data, due to the lack of data about the embankments soil structure. Also, the groundwater level measures applied in this research were based on 2001.
In conclusion, these research results are still could be improved by applying site analyses. In these analyses, a geotechnical test carried to measure the groundwater and to check the embankment soil structure.
