Abstract：Research purposes: In order to investigate the effect of different construction methods on the settlement lawof subgrade in the regions of high salt saturated fine sand and provide theoretical basis and application guidance for the foundation treatment， the subgrade filling and the subgrade disease control in the similar areas， based on practical engineering，field test and numerical simulation，a comparative analysis on the subgrade settlement law and deformation mechanism was carried out under different subgrade treatment methods. Research conclusions:(1) The prepressing treatment of subgrade can accelerate the settlement of the subgrade into the steady state. (2 ) The method of not digging out salt crust can reduce the settlement after construction of subgrade，whicli put the rolling process on salt crust directly and then start subgrade filling. ( 3 ) According to the principle of track - laying after basic stability of subgrade settlement，it is recommended that the reasonable time for upper structure laying should be 180 days after the project completion. (4) The research results can be used in some saline soil subgrade engineering.
