摘要
采用ADINA软件对直立式加筋土挡土墙的变形机制进行有限元数值模拟分析.通过数值模拟分析,对加筋土挡墙等效塑性应变、水平位移及墙面板变形的分布规律进行探讨,为保证计算精度,程序采用8节点的四边形单元对挡墙的稳定性进行分析.分析结果表明,在土坡中设有加筋,可以有效地改善土坡的工作性能,可以使其水平位移协调、均匀,加筋能明显提高挡土墙的稳定性.
The deformation mechanism of vertical reinforced retaining wall was simulated and analyzed by using software for ADINA finite element numerical computation.The equivalent plastic strain,horizontal displacement and distribution pattern of the wall plate are explored.In order to ensure the calculation precision,the quadrangular element with 8 nodes was used in the program to analyze the stability of the retaining wall.The result showed that the reinforcement could obviously improve the working performance of the soil slope and make the horizontal displacement coordinative and uniform.The reinforcement could significantly improve the stability of the retaining wall.
