摘要以大理至瑞丽铁路沿线边坡支挡结构为研究对象，以汶川波作为输入地震波，对基覆(厚覆盖层和基岩)边坡的3种不同支挡结构在地震荷载下的动力特性进行数值模拟和振动台模型试验，再对比分析二者结果，主要研究基覆边坡在压缩汶川波XZ双向激励下支挡结构基覆边坡加速度响应规律，研究表明：数值结果与振动台模型试验结果规律基本一致，3种支挡结构的水平向加速度放大系数随着挡墙高度的增加而变大；锚杆框架梁竖向加速度放大系数随测点高度的增加均有增大的趋势；对于地震加速度响应特性而言，振动台模型试验的结果是合理的，数值模拟的结果是可靠的，但数值模拟值稍偏大。

Abstract：Based on the supporting structure of the railway from Dali to Ruili and the Wenchuan earthquake excitation，the dynamic characteristics of 3 kinds of retaining structures against slopes of bedrock and overburden layer were studied with the methods of numerical analysis and shaking table experiment. The responsive acceleration under the action of input XZ-excitation of Wenchuan earthquake is the main focus in the study. The results from two methods are found to be largely similar to each other. The horizontal acceleration of three types of retaining walls increases with the height of retaining wall increasing，and the vertical acceleration on anchor frame beam increased with the height of monitoring point rising. So，as far as the earthquake acceleration is concerned，the shaking table test is reasonable and the numerical modeling is reliable. However，the results of numerical modeling are slightly bigger.

Key words： slope engineering bedrock and overburden layer slopes numerical analysis with FLAC3D shaking table test acceleration amplification coefficient
