摘要

加筋土挡墙作为一种新型的轻型支挡结构，广泛应用于公路、铁路、港口等工程中。随着加筋土挡墙技术的发展，面板的类型也越来越丰富。利用Plaxis有限元软件，对路堤式加筋土挡墙进行了二维有限元计算分析。针对墙背水平土压力、垂直土压力、挡墙侧向位移、筋材应变和挡墙稳定系数等计算结果的分析，探讨了3种类型面板（返包式面板、整体式面板和拼装式面板）对路堤式加筋土挡墙力学性能的影响。研究结果表明，垂直和水平土压力的数值计算结果均小于理论值；相比较与其他两种面板的加筋土挡墙，返包式面板加筋土挡墙筋材的应变最大；面板类型对于加筋土挡墙的整体稳定性几乎没有影响。研究成果为实际工程的应用提供了理论指导。

Abstract

As a new light-retaining structure

the reinforced earth retaining wall has been widely used in roads

railways and ports. And with the rapid development of the technology of reinforced earth retaining wall

the types of facing are also more and more abundant. A two-dimensional (2D) finite element analysis is conducted to simulate a reinforced earth retaining wall for embankment by using the finite element software Plaxis. To investigate the influence of different facing types on the mechanical behavior of the reinforced earth retaining wall for embankment

the calculated results of reinforced earth retaining wall with three facing types (wrapped facing

overall facing and assembled facing) are analyzed

including the lateral earth pressure

the vertical earth pressure

the lateral deformation of retaining wall

the strain of reinforcement

and the factor of stability. It is found that the numerical results of vertical and lateral earth pressures are less than theoretical results. The reinforced earth retaining wall with the wrapped facing has a larger strain than those with the other two facing types. Furthermore

the three facing types have little influence on the overall stability of reinforced earth retaining wall. These results provide theoretical guidance for engineering application.
