Application of retaining wall with vertical prestressed anchors in high fill slope engineering

文章以垂直预应力锚杆式挡墙在某道路改造工程高填方边坡支护中的优化设计为案例,介绍了垂直预应力锚杆式挡墙的作用原理及技术经济优势。通过分析面坡斜坡坡度、填土内摩擦角、基底摩擦系数、锚杆施加预应力等不同参数的选取对挡墙稳定性的影响,探讨得出增强挡墙抗滑移、抗倾覆稳定性的优化设计措施,旨为类似条件下的边坡设计提供参考。

Based on the optimization design of the retaining wall with vertical prestressed anchors in high side fill slope protection of certain road reconstruction project,the work principle of the retaining wall with vertical prestressed anchors and its technical and economic advantages are introduced.The influences of different parameters such as the slope gradient,the internal friction angle of the fill,the friction coefficient of the base and the prestressing of anchors on the stability of retaining wall are analyzed,and the optimal design measures to enhance the anti-sliding and anti-overturning stability of the retaining wall are obtained.The purpose is to provide the reference for similar slope design.
