摘要

根据南宁市防洪堤岸坡岩土材料的特性，对典型堤段的岸坡岩土材料进行了试验研究。根据试验数据拟合得到体积屈服面和剪切屈服面，基于广义塑性力学原理，建立了岸坡岩土材料的本构模型。使用MATLAB程序进行数值计算，通过对比试验曲线和理论曲线的拟合程度检验了模型的合理性。

Abstract

Based on the characteristics of slope geomaterial for in the flood-wall in Nanning city’s

experimental investigation has been finished in typical bank. The experimental data are used for fitting the volume yield surface and shear yield surface

the constitutive model based on the principle of generalize plasticity is then built . MATLAB is used for numerical simulation; and the rationality of this model is verified by comparing the test curves and theoretical ones.
