本文根据上海粘土的真三轴试验结果,对上海粘土弹塑性应力—应变模型的建立进行探讨,并研究了确定有关参数的方法。试验表明,模型中的参数均可通过常规三轴试验加以确定,这使上海地区采用弹塑性模型研究粘土成为可能,本文最后还利用该模型所得的计算值与试验结果作了对比,取得了较理想的效果。 Based on the true triaxial test results of Shanghai clay, this paper discusses the establishment of elasto-plastic stress-strain model for Shanghai clay, and studies the methods for determining the relevant parameters. The test shows that the parameters in the model can be determined by conventional triaxial tests, which makes it possible to study clay in elasto-plastic models in Shanghai. Finally, the comparison between the calculated values ​​obtained from this model and the experimental results is obtained. Ideal effect.
