摘要
多级边坡在实际工程中普遍存在滑坡、边坡稳定性低等问题,为研究多级加筋土挡墙在工程实践中的应用.本文基于已有研究成果,通过实地考察和模型试验,进行了深入研究.通过模型试验并运用slide软件进行边坡稳定性及滑动面模拟计算,研究了不同加筋条件下多级加筋土挡墙的工作性能,分析了加筋材料、加筋层数、加筋间距等因素对挡墙稳定性和变形特性的影响.结果表明,加筋材料和层数间距可以改变边坡的摩擦角,提升土体的整体稳定性,在锚杆支护条件下安全系数总体可以提高111%.
Abstract
In practical engineering,there are common problems such as landslides and low slope stability in multi-level slopes.To study the application of multi-level reinforced soil retaining walls in engineering practice.This article is based on existing research results and conducts in-depth research through field investigations and model experiments.By conducting model ex-periments and using slide software to simulate slope stability and sliding surface,the working performance of multi-level rein-forced soil retaining walls under different reinforcement conditions was studied.The effects of reinforcement materials,rein-forcement layers,and reinforcement spacing on the stability and deformation characteristics of the retaining walls were ana-lyzed.The results show that reinforced materials and interlayer spacing can change the friction angle of the slope,improve the overall stability of the soil,and increase the overall safety factor by 111%under anchor rod support conditions.
