    摘要：泡沫混凝土是一种轻质材料，多运用于桥台台背回填、路堤边坡置换等分项工程，由于其材料的特殊性，在控制路基沉降方面有着天然的优势。针对路用泡沫混凝土对地基应力应变的影响进行研究，并通过数值模拟得出泡沫混凝土力学性能的变化规律，将理论计算结果与模拟结果进行对比，并分析误差产生的原因。为类似项目的施工提供参考和借鉴。

    Abstract：Foamed concrete is a kind of lightweight materials，more used in bridge abutment back backfilling，embankment slope displacement and other kinds of construction，due to the particularity of its material，it has a natural advantage in terms of control of subgrade settlement. This paper studied the effect of pavement-based foamed concrete on the stress and strain of subgrade，obtained the change rule of the foamed concrete mechanical parameters through the numerical simulation，compared the theoretical calculation results with the simulation results，and analyzed the cause of error produced，providing a reference for similar project construction.
