Settlement of HSR embankment

SETTLEMENT OF HIGH-SPEED RAILWAY (HSR) EMBANKMENTS FROM FEM ANALYSIS Van-Ngoc Pham This dataset is the settlement of High-speed railway (HSR) embankments under various input conditions. Stiffened deep cement mixing (SDCM) piles, in combination with geogrids, were investigated as a ground improvement technique. Python scripting was developed to run multiple analyses in PLAXIS, considering a wide range of embankment height, soft soil thickness, SDCM diameter, SDCM length, train load, and train speed. As a result, 324 points of data on the settlement of the HSR embankments in various scenarios were recorded. Table 1. Variable parameters in the HSR improved embankment.
