摘要
加筋土挡墙通常采用规范的0.3H(单楔体)法设计,该法计算简单,但它仅验算一个破裂面,不能考虑其它潜在破裂面以及结构的可靠性。DIBt法是德国设计者提出的一种双楔体法,它能验算出位于不同高度和不同角度潜在破坏面,具有明显可靠性。文章结合某变电站进站道路加筋土挡墙工程,主要介绍DIBt法加筋土挡墙的结构设计方法、稳定性验算理论,并对其工程应用提出了建议,这将为今后加筋土挡墙的设计提供指导和借鉴。
Though 0.3 H （namely single-wedge block） method is usually adopted for reinforced earth retaining wall because of its simplicity, it calculates only one broken plane stability but fails to consider other potential bro- ken planes and structural reliability. The DIBt method based on double-wedge block, which is advanced by Ger- man designers, can check up with distinctive reliability multi-potential broken planes with various heights and base angles. Combined with one pulling-in road with reinforced earth retaining wall for transformer substation, structure designing procedure and stability analysis theory of reinforced earth retaining wall are introduced in details based on DIBt method. Furthermore, some constructive advices are also given for its practical application. This can act as a guidance and reference for structural design of reinforced earth retaining wall.
