Dynamic problems of fluid‐saturated soils have to be assessed through a complete formulation where dynamic terms take place. The main dynamic Biot's formulation, the $u-w$, is employed widely in the literature in order to accurately study the dynamic phenomena. However, depending on the spatial discretization this formulation is utilizing, numerical errors may appear within this approach. The proposed methodology, which is presented in this research, aims to solve the aforementioned problems within an elegant algorithm. Two interesting environmental applications, a consolidation of a fluid‐saturated soil and the seepage of the water through an earth dam, are presented in this paper.

u-w Biot制剂在大应变下的流体稳定性

流体饱和土的动力学问题必须通过一个完整的公式来评估，其中要使用动力学术语。动态比奥的主要配方，$ü-w$为了准确地研究动态现象，在文献中被广泛使用。但是，根据此公式所利用的空间离散化，此方法中可能会出现数值误差。这项研究中提出的方法论旨在在一种优雅的算法中解决上述问题。本文介绍了两个有趣的环境应用，即饱和流体的固结和水通过土坝的渗流。
