在岩土工程中，模拟是至关重要的。由于大变形，无网格方法比经典的基于网格的方法更适合。然而，它们必须在实验室规模上进行验证，以保证可靠的结论适用于真实的生活应用。在本文中，我们完成了两个新的无网格广义有限差分方法有限点集方法（FPM）和软粒子代码（SITE）的理论描述，通过标准的基准问题的数值结果oedometric和三轴试验。我们专注于质量的结果，以及在率独立字符的数值实现的非线性气压模型沙。
In geotechnical engineering, simulations are of utmost importance. Due to large deformations, meshfree methods are more suitable than classical meshbased methods. Nevertheless, they have to be validated on the laboratory scale in order to guarantee reliable conclusions for real life applications. In this contribution, we complete the theoretical description of the two novel meshfree generalized finite difference methods Finite Pointset Method (FPM) and Soft PARticle Code (SPARC) by numerical results for the standard benchmark problems oedometric and triaxial test. We focus on the quality of the results as well as on the rate-independent character of the numerical implementation of the nonlinear barodesy model for sand.
