摘要
结合远安至当阳一级公路改建工程中采用的双面加筋挡土墙结构,以非线性有限元法对其结构特性进行了分析,并用Drucker—Prager模型模拟土体材料的非线性,研究分析了拉筋拉应力及墙背土压力沿墙高的分布规律,有限元分析结果与现场实测值吻合良好。研究表明,双面加筋挡土墙结构明显不同于一般重力式挡土墙,研究成果对其工程应用和进一步推广提供参考。
Combined with the structure of double reinforced retaining wall applied in reconstruction engineering of Yuan＇ an-Dangyang Arterial Highway, this paper carries out analysis on its structural characteristics with nonlinear finite element method and simulates the nonlinearity of soil materials with Drucker-Prager Model to study the distribution rule of reinforced stress and wall back soil pressure along wall height. Finite element analysis result tallies closely with site measurement value. It is indicated that the structure of double reinforced retaining wall is obviously different from that of common gravity retaining wall. The result provides reference for engineering application and further promotion.
