摘要
根据上海典型粘性土的平面应变不排水压缩试验,观察了剪切带的形成和发展过程,并结合有限元数值模拟再现剪切带的形成过程,对剪切带形成机理作了探讨。
Based on the results of undrained plane strain compression test for Shanghai's typical clay, the formation and development of shear band were observed. In order to study the mechanism of formation of shear band the load test was simulated numerically by using the finite element method under the condition of finite strain. The internal wear element and external imperfection boundary mode were introduced for exciting shear band. Finally, the mechanism of formation was discussed.
