To evaluate residual settlement of the high-speed railway trackbed, it is hard to apply immediately settlement analysis because in-situ ground has additional creep or secondary consolidation behavior. To select the settlement analysis method, this study compared measurement data with hyperbolic, Asaoka, Hoshino method result. All residual settlement analysis method has a tendency to be underestimated because of in-situ creep behavior, however all the method are reliable because R2 is high(over 0.94) and RMSE(Root Mean Square Error) is low. The additional measurement data comparison shows that hyberbolic method is the most appropriate method with high accuracy and application.
