双面加筋挡土墙结构受力特性的数值模拟分析

结合某公路扩建工程中采用的双面加筋挡土墙结构,采用有限元法对该挡土墙的受力特性进行数值模拟分析,计算中采用Drucker-Prager模型模拟土体材料的非线性,研究分析拉筋拉力及墙背侧向土压力的分布规律,有限元分析结果与现场测试值具有较好的一致性,分析成果对该挡土墙的推广应用提供了重要的参考价值。

Numerical Analysis on the Stress of the Double Reinforced Retaining Walls

While taking into consideration of the double reinforced retaining wall structure built as part of a certain highway expansion,this paper discusses the stress distribution on retaining walls using numerical simulated analysis.The Drucker-Prager Model is chosen to simulate the non-linearity of soil,the distribution law of the lateral earth pressures on the facing and tensile force of the reinforcements are analyzed and studied.The results of the finite element method(FEM),in accordance with the in-site measurement,can be used as a reference for future further application and dissemination.
