摘要

在地震作用下，加筋土挡墙作为一种柔性结构，常因水平位移过大影响其正常使用，因此，提出一种有效的解析方法来计算加筋土挡墙在地震作用下的水平位移显得尤为重要。基于动力作用下墙后填土的不同运动特性，将地震作用下加筋土挡墙水平位移进行分区计算，并讨论了不同区域影响土体位移的关键因素。分别以Mindlin位移理论和拟动力法为基础，以筋土无相对位移为前提，提出了地震作用下不同区域位移的计算方法，并分析了未考虑筋土相对位移对计算结果的影响。该方法通过离心模型试验得到进一步验证，可用于大多数加筋土挡墙的地震动力分析中，可为加筋土挡墙的动力设计和稳定性分析提供一定的依据。

Abstract

As a flexible structure

reinforced earth retaining walls have been widely used in the field of civil engineering. However

excessive horizontal displacement of reinforced earth retaining wall due to earthquake could affect its service performance. Therefore

it is very important to develop an effective analytical method to calculate the horizontal displacement of reinforced earth retaining wall under earthquake. The reinforced earth retaining wall was divided into two regions for calculation based on the different movement characteristics of the backfill behind the wall. The key factors affecting the horizontal displacement of the reinforced earth retaining wall in different regions were discussed. Based on Mindlin displacement theory and pseudo-dynamic method

the calculation method of horizonal displacement in different regions under the earthquake

under the assumption of no soil-reinforcement relative slippage

was proposed and the influence of soil-reinforcement relative slippage on calculated results was studied. This method is further verified by centrifuge model test and can be used in the seismic dynamic analysis of general reinforced earth retaining walls. This provides basis for the dynamic design and stability analysis of reinforced earth retaining walls.
