Application and Model Test Analysis of Multi level Reinforced Soil RetainingWall in Engineering

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%。

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 experiments 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 analyzed.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.
