The paper relied on Chaerhan~Geermu highway in Qinghai province,Part of the projectthrough the poor geological sections of the Salt Lake. According to hydrogeologicalconditions and the actual project needs in Yanhu area,designing the field test of thefoundation settlement of soft soil salinization in scientific research section. By means oftaking an observation of ground settlement、pressure and moisture of soil for one year,a lot ofvaluable field test data was acquired. Based on the data,and from the theoretical analysiscombined with field testing as well as other aspects,foundation settlement characteristics andsettlement calculation methods was studied. foundation settlement regularity of soft soilsalinization in Yanhu area was analyzed in the two foundation treatment methods. The resultshowed that both methods have achieved good results,and the trend of settlement curve isbasically consistent. it was suitable for use in Yanhu area,and what’s more,using the curvefitting method to predict the final settlement of foundation. Based on the measured data,thetwo fitting methods were calculated and contrasted,and getting the suitable forecastingmethod in the area. Finally,the change of pressure and moisture of soil respectively on theinfluence of foundation settlement was discussed. The study of the essay can offer the help toother similar projects in Yanhu area.
