In order to study the deformation of high fill in the Dalin Railway Station, a typical cross-section was selected. Four rows of settlement plates and slope observation piles were buried in the high fill, and flexible displacement meters were installed on the geogrid at the foot of the slope. After more than two years of observation, it was found that after more than half a year of construction and filling, as well as more than 12 months of standing after completion, the settlement of the high fill tended to stabilize. The maximum percentage of settlement during the filling period to the total settlement is 69.05%. The test results of the observation piles on the left and right slopes show that the high fill slope is also stable, and the maximum proportion of settlement during the filling period is 99.77% of the total settlement. After the filling is completed, the deformation of the geogrid is basically stable, indicating that the slope is also stable. It is recommended to carry out subsequent construction 12 months after the completion of filling.
