无面板式高陡加筋土挡墙的变形特性分析

Analysis of deformation characteristics of steep reinforced earth retaining wall without concrete panel

在高陡填方区采用土工格栅加筋土挡墙,容易产生较大变形,且至变形稳定持续时间长。文章以某填方边坡为例,对无面板式加筋土挡墙的变形性状进行分析,分析结果表明,无面板式高陡加筋土挡墙的大变形,主要是地质条件、填料及土工格栅材料、施工条件、面板等综合影响。基此,提出了防患加筋土挡墙变形的相应建议。

Large but steady deformation may occur, when reinforced earth retaining wall with geogrid is used in the tall and steep fill region. The deformation characteristics of the reinforced earth re- taining wall without concrete panel was mainly expounded via a fill slope case. The influence of geolo- gical conditions, materials of the filler and geogrid, the execution conditions and the concrete panel was also analysed. It is indicated that the results may be applied in similar retaining walls.
