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。
The initial smoothing data of centrifuge soil was performed, and the displacement field and strain field were constructed by patch interpolation. For the calculation model obtained from the triaxial test, a corresponding positive analysis finite element program was compiled to simulate the actual project. The calculated results are consistent with the measured displacement data and can be used to evaluate the stability of the foundation. The prospect of determining the yield zone from the measured strain field is discussed, and a backward analysis path from measured displacement-strain-stress is proposed.
