Different projects have different requirements for post-work settlement.The inconsistent understanding of unloading standards encounters in the process of soft foundation treatment.Relying on an actual project,we use the hyperbolic method,three-point method and Asaoka method to calculate and analyze respectively.The results show that the unloading standard is more reasonable with consolidation degree as the main and settlement rate as the supplementary.The prediction result of three-point method is larger when calculating the consolidation degree,and it is appropriate to choose the points with the time interval of 25 d in the gentle section of curve.The prediction result of hyperbolic method is smaller,but the human influence is large,and it is necessary to exclude the previous data and anomalous data in the fitting.The Asaoka method is appropriate to choose the interval of 5 to 10 d,so as to be in good accordance with the actual measurement results.In actual projects,it is necessary to combine a variety of methods and actual observation data to comprehensively judge the degree of soft soil consolidation,in order to improve the accuracy and reliability of the prediction.
