| 摘 要： | 随着基础设施的进一步发展,高路堤加筋土挡墙修筑需求增大,而高路堤加筋土挡墙受力变形较一般路堤加筋土挡墙复杂,目前对其研究较少。为研究高路堤加筋土挡墙的受力变形特性,采用实际的工程图集案例,运用有限元分析方法,建立有限元模型,通过改变结构设计参数的单一因子,分析填料、加筋率、平台宽度等主要设计参数的敏感性,筛选出满足稳定性要求的设计参数取值范围,实现高路堤加筋土挡墙的优化设计。

Numerical Simulation Analysis of Deformation of High Embankment Reinforced Soil Retaining Wall under Stress |
| |
| Abstract: | With the further development of infrastructure construction, the demand of high embankment reinforced soil retaining wall increases rapidly.However, the mechanical deformation of high embankment reinforced soil retaining wall is more intricate than that of general embankment reinforced soil retaining wall, which leads to less research on it at present.To make research on mechanical deformation of high embankment reinforced soil retaining wall, the actual engineering atlas cases are adopted with the finite element analysis method, the finite element model is established.By changing the single factor of structural design parameters, analysis of sensitivity of main design parameters like filling, reinforcement rate, platform width, etc., the scope of design parameters meeting the stability requirement is selected so as to realize the optimization design of high embankment reinforced soil retaining wall. |
