| 摘 要： | 应用有限元方法分析了在爆炸载荷作用下地下圆形结构与土介质的动力相互作用问题。结构与土介质均假定为弹塑性，并用Ｍｉｓｅｓ屈服准则描述，而且考虑其几何非线性的影响。文中使用了人为阻尼边界和模型几何尺寸限制条件，从而大大提高了计算精度。文中还对几种解进行了比较和讨论

| Abstract: | In the paper, the problem of interaction between soil media and an underground round structure to explosive loading is studied by FEM. The behavior of the structure and the media is described by the elastoplastic model with Von. Mises yielding criterion, and the influence of geometric nonlinearity of them is considered. In the paper artificial viscous absorbing boundary and the limited condition of the geometric size of the model are used. Thus the calculating precision is greatly increased. In the paper, several solutions are also compared. |
