散粒体道床离散单元法分析

Using of distinct element method to analyze granular ballast bed

:探讨散粒体道床新的数值分析方法——离散单元法 ,建立道床离散单元模型 ,计算散粒体道床在不同加载情况下道床的应力 。

A new numerical method distinct element method is firstly discussed to apply to granular ballast bed in this paper. We build ballast's distinct element model and calculate ballast's stresses in different loads,at the same time analyze these results.
