Abstract

This paper reviews numerical methods used to simulate desiccation cracks in clayey soils. It examines five numerical approaches: Finite Element (FEM), Lattice Boltzmann (LBM), Discrete Element (DEM), Cellular Automaton (CAM), and Phase Field (PFM) Methods. The paper presents a simplified description of the methods, including their basic numerical formulations. Several factors such as the multiphase nature of soils, heterogeneity, nonlinearities, coupling, scales of analysis, and computational aspects are discussed. The review highlights the characteristics, strengths, and limitations of each method. FEM shows a good capacity to deal with the thermo-hydromechanical behavior of clays when drying that complement well with the ability of DEM to deal with particle interactions as well as LBM, PFM, and CAM to deal with complex crack patterns. The article concludes by reviewing the integration of multiple numerical methods to enhance the simulation of desiccation cracks in clayey soils and proposing what is the best option to continue improving the study of this problem.

粘性土干裂解决方法综述

本文综述了用于模拟粘性土干裂的数值方法。它检查了五种数值方法:有限元(FEM)，晶格玻尔兹曼(LBM)，离散单元(DEM)，元胞自动机(CAM)和相场(PFM)方法。本文给出了这些方法的简化描述，包括它们的基本数值表达式。几个因素，如土壤的多相性质，非均质性，非线性，耦合，分析尺度和计算方面进行了讨论。这篇综述强调了每种方法的特点、优势和局限性。FEM在处理粘土干燥时的热流体力学行为方面表现出良好的能力，与DEM处理颗粒相互作用的能力以及LBM、PFM和CAM处理复杂裂纹模式的能力相补充。文章最后回顾了多种数值方法的结合，以加强对粘性土干燥裂缝的模拟，并提出了继续改进这一问题研究的最佳选择。
