摘要
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。
In this paper, a series of consolidated-undrained true triaxial tests for Shanghai clay has been performed. Based on the test results, an eiastoplastic model for Shanghai clay has been presented The methods for determining parameters in model are also presented in this paper. The test results show that the parameters in model are all determined by conventional trixial tests. The calculated results agree quite closely with the test results, which is helpful to the calculation of foundation settlement for clay in Shanghai.
