Nu merical si mu lation on dyna mic behavior of reinforced earth retaining wall
摘要
Abstract
Based on laboratory model tests,a finite element program (FEP)was developed to analyze the dynam-ic behavior of a reinforced earth retaining wall.In the FEP,the interaction between the soil and the reinforce-ment materials was simulated by an interface element.The results obtained via the finite element method agreed well with the model test results.It was revealed that the variation trend of the increment of pullout force of the re-inforcement materials increases with the input dynamic force.In addition,under the application of dynamic force,the accelerations of soil elements in the reinforced earth retaining walls were considerably increased as compared to the input acceleration of the ground.The findings of this study can provide useful references for the design of reinforced earth retaining walls in similar earthquake regions.关键词
