摘要
对离心机土体实测数据进行了初步光顺，并分片插值构造了位移场和应变场。对三轴试验得到的计算模型，编制了相应的正分析有限元程序，用以模拟实际工程。其计算结果与实测位移资料一致，可用以对地基稳定性作评估。探讨了由实测分析的应变场判定屈服区的前景，并提出了一种由实测位移—应变—应力的反分析途径。
Though the analysis of the measured displacement from geotechnical centrifugal modeling, this paper accomplished the formation of displacement field and strain field. A feasible numerical model to the stability analysis of Shanghai soft soil is given out through the analysis of triaxial tests of centrifuge consolidated soil sample. The implementation of the experimental data of centrifugal modeling with the above method shows little difference with the calculated displacement and observed displacement in estate site in neither pattern nor amount.
