摘要
利用有限元分析软件ABAQUS,采用Hill理想弹塑性本构模型,对软基上大圆筒结构在单调加载条件下的失稳破坏机制进行了数值模拟,得出了一些有益的结论。
By using the finite element software ABAQUS,the failure mechanism of the largediameter cylindrical structure in soft soil foundation under monotonic loading is numerically analyzed,in which the soil is assumed to obey the Hill's yield criterion.
