摘　　要：轻质泡沫混凝土因其低密度、高孔隙率及优异的力学性能,成为填方路基材料的理想选择。本文旨在研究轻质泡沫混凝土在填方路基中的应用。通过理论分析、数值模拟及现场试验三种方法,评估其稳定性。理论分析基于莫尔-库仑破坏准则计算抗剪强度,数值模拟使用ABAQUS软件模拟自重及交通荷载作用下的应力分布和变形情况,现场试验则通过监测和加载试验验证设计方案的可行性。研究结果显示,轻质泡沫混凝土路基在实际工程中表现出良好的稳定性和耐久性。Lightweight foamed concrete,characterized by its low density,high porosity,and excellent mechanical properties,has become an ideal material for embankment construction.This paper aims to study the application of lightweight foamed concrete in embankment construction.The stability of foamed concrete embankments is assessed through three approaches:theoretical analysis,numerical simulation,and field testing.The theoretical analysis is based on the Mohr-Coulomb failure criterion to calculate shear strength.Numerical simulations are conducted using ABAQUS software to model stress distribution and deformation under self-weight and traffic loads.Field tests are performed to verify the feasibility of the design scheme through monitoring and loading experiments.The research results show that foamed concrete embankments exhibit good stability and durability in practical engineering applications.
