    摘要:

    不同工程对于工后沉降的要求不同。依托实际工程,结合软基处理过程中遇到的卸载标准理解不一致的问题,采用双曲线法、三点法、Asaoka法分别进行推算分析。结果表明:以固结度为主、沉降速率为辅的卸载标准较为合理;推算固结度时三点法预测结果较大,取点时选取曲线平缓段时间间隔25 d为宜;双曲线法预测结果较小,但人为影响大,拟合时需要对前期数据和异常数据进行剔除;Asaoka法选取5~10 d间隔为宜,与实测结果较吻合。实际工程中,需要结合多种方法和实际观测数据,综合判断软土固结度,以提升预测的准确性和可靠性。

    Abstract:

    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.
