A smoothed particle hydrodynamics code based on micropolar continua for geomaterials is developed for problems involving large deformation and shear strain localization. Two typical geotechnical problems, i.e., biaxial compression test and sand column collapse, are simulated using classical and micropolar model to demonstrate the performance of the newly proposed method. A parameter study is given on the scale effect in the micropolar continua.

微极SPH在地质力学中的应用

针对涉及大变形和剪切应变局部化的问题，开发了一种基于微极连续体的光滑粒子流体动力学代码，用于地质材料。使用经典和微极模型模拟了两个典型的岩土工程问题，即双轴压缩试验和砂柱倒塌，以证明新方法的性能。对微极连续体中的尺度效应进行了参数研究。
