Analysis of the breakage parameters of railway ballast based on the discrete element method

Journal of Zhejiang University: Science A, 2022
目的 有砟轨道在长期服役下频繁出现道砟颗粒掉角、破碎等劣化现象,降低了有砟轨道的稳定性。而道砟的破碎与其形状、大小、应力状态等有较大的关系,因此合理确定道砟的破碎参数是研究和解决这一问题的关键。本文旨在探索基于Hertz-Mindlin本构模型的道砟破碎参数,研究道砟的破碎性能,以期为实际服役的铁路有砟轨道提供参考。 创新点 1. 采用统计学方法分析了道砟破碎的主要影响因素及其临界压碎强度和临界剪碎强度;2.
