| 摘 要： | 为研究连云港海相软土流变特性，进行了三轴流变试验。根据对试验结果的分析，可以将连云港海相软土作为弹-粘塑性体来研究；将广义Bingham模型和椭圆-抛物线双屈服面模型相结合，建立了新的流变模型来描述其流变特性，得出了各参数，并验证了该模型的适用性。

| Abstract: | In order to investigate the rheological properties of Lianyungang soft marine clay, a triaxial rheological test is performed. Based on the analysis of laboratory tests, Lianyungang soft marine clay can be regarded as an elastic-viscoplasticity. Then, the generalized Bingham model and the ellipse-parabola two-yield-surface model are combined to develop a new rheological model to describe its rheological behavior. Finally, all the parameters are obtained and the applicability of this model is validated. |
