本研究旨在对轻骨料混凝土在动态受压条件下的性能进行数值模拟分析。基于基面力元法对轻骨料混凝土的细观力学性能进行分析，考虑了材料的非线性行为和加载应变率条件。研究结果表明，随着加载应变率的增加，轻骨料混凝土试件的材料非线性逐渐减小，同时轴向抗压强度略有提高。此外，分析了不同参数对混凝土性能的影响，为优化设计提供了有力的参考。本研究的方法为轻骨料混凝土在动态荷载下的工程应用提供了一种有效的分析手段，在轻骨料混凝土工程应用的数值仿真模拟分析中具有广阔的应用前景。This　study　aims　to　perform　a　numerical　simulation　analysis　of　the　performance　of　lightweight　aggregate　concrete　under　dynamic　compression　conditions.　The　micro-mechanical　properties　of　lightweight　aggregate　concrete　are　analyzed　using　the　discrete　element　method,　taking　into　account　the　nonlinear　behavior　of　the　material　and　the　loading　strain　rate　conditions.　The　results　indicate　that　as　the　loading　strain　rate　increases,　the　material　nonlinearity　of　lightweight　aggregate　concrete　specimens　gradually　decreases,　while　the　axial　compressive　strength　slightly　improves.　Additionally,　the　impact　of　different　parameters　on　the　performance　of　the　concrete　is　analyzed,　providing　a　strong　reference　for　optimized　design.　The　methodology　of　this　study　offers　an　effective　analytical　tool　for　the　engineering　application　of　lightweight　aggregate　concrete　under　dynamic　loads,　and　it　holds　broad　application　prospects　in　the　numerical　simulation　analysis　of　engineering　applications　of　lightweight　aggregate　concrete.
