【摘要】 根据广义平面应变问题具有所有物理量沿某一方向变化为零的特点,针对连续、各向异性两相饱和介质,在变形满足小变形、孔压流满足达西定律、有效应力原理成立的假定下,建立以增量形式的三向荷载作用下液固耦合作用的平面有限元分析方法.更多还原

【Abstract】 Based on the properties of the generalized plane strain problem, in which the total variation of all variables in a certain direction is equal to zero, a 2D FEM with incremental variables was developed for the liquidsolid coupling problem under 3D imposed loads. In the analysis, it was assumed that the medium was continuous, anisotropic, and saturated, Darcy’s law held valid and the effective stress principle held true.更多还原
