摘要
结合实际工程的建设,实测了土工格栅加筋挡土墙不同填土高度时的拉筋应变;同时,应用ADINA非线性有限元软件,对土工格栅加筋挡土墙的拉筋应变进行了有限元数值计算与分析。结果表明:有限元计算值与实测结果相一致,证明了ADINA有限元方法的合理性与可靠性,为土工格栅加筋挡土墙的设计、理论分析与工程应用提供了依据。
The strains of tensile bars in the reinforced earth retaining walls with geogrid at different fill height were measured during the construction of projects, while calculation and analysis on these strains were made with nonlinear finite element ADINA software. The results indicate that the calculated value is consistent with the measured results and ADINA method is reasonable and reliable, thus providing a basis for design, theoretic analysis and engineering application.
