随着计算条件的不断发展，颗粒离散元方法在岩土工程数值分析中已有一定应用。在真实条件下，颗粒形状往往较为复杂，因此对复杂颗粒形状的模拟在研究岩土颗粒材料物理力学特性中至关重要。简要阐释了目前颗粒离散元法在岩土工程中的应用现状，并重点分析了离散元模拟颗粒形状的两方面：模拟典型颗粒形状，模拟真实颗粒形状；同时根据已有研究总结离散元模拟颗粒形状方法存在的一些问题，提出颗粒形状模拟在岩土工程中的应用前景。

The particle discrete element method has been gradually applied to geotechnical engineering with the development of the ability to calculate. Complex particle shapes are commonly found in nature, making it crucial to investigate the physical and mechanical properties of rock and soil granular materials. In this context, in order to discuss the current application status of the particle discrete element method in geotechnical engineering. Furthermore, two ways of simulating particle shapes in the discrete element method were introduced. The simulation of typical particle shape. The simulation of real particle shape. The problem of the discrete element method was summarized based on existing research results, and the simulation of particle shapes in the application prospects of geotechnical engineering using the discrete element method was proposed.
