摘要

虚元法(VEM)因其具有求解任意节点网格的能力而在工程中得到广泛应用。在这项研究中，我们提出了一种利用向量机的优点来确定土石混合边坡无侧限渗流问题的自由面方法。通过在迭代中切割网格，克服了固定网格在求解自由面时的局限性，数值试验验证了该方法预测渗流面位置的准确性。此外，研究结果表明，岩石块体的存在显著影响土石混合边坡的无侧限渗流行为，揭示了在土石混合体系分析中考虑岩石块体的重要性。

Simulation of unconfined seepage in soil–rock mixture slope by virtual element method

The virtual element method (VEM) is commonly used in engineering due to its ability to solve arbitrary node meshes. In this study, we propose a method to determine the free surface of the unconfined seepage problem in soil–rock mixtures slope using the advantages of the VEM. By cutting meshes in the iteration, our method overcomes the limitation of fixed mesh in solving the free surface, and the numerical tests confirm the accuracy of the proposed method in predicting the location of the seepage surface. Moreover, the results demonstrate that the presence of rock blocks significantly impacts the unconfined seepage behavior of soil–rock mixtures slope, revealing the importance of considering rock blocks in the analysis of such systems.

期刊介绍： The objective of the Journal of Mechanics is to provide an international forum to foster exchange of ideas among mechanics communities in different parts of world. The Journal of Mechanics publishes original research in all fields of theoretical and applied mechanics. The Journal especially welcomes papers that are related to recent technological advances. The contributions, which may be analytical, experimental or numerical, should be of significance to the progress of mechanics. Papers which are merely illustrations of established principles and procedures will generally not be accepted. Reports that are of technical interest are published as short articles. Review articles are published only by invitation.
