摘　　要：随着高速公路建设规模的持续扩大,高填方路基的施工质量至关重要。文章依托实际工程项目,结合现场复杂的地质条件,利用FLAC3D数值模拟软件对高填方路基的稳定性展开研究。研究表明,在高填方路基施工中,应当严格筛选填料、精准测量放样及规范沉降监测,以保障施工质量;数值模拟发现,在路基顶部及坡脚位置出现较大的位移值,且安全系数为1.12,稳定性欠佳。为此,提出浆砌拱形骨架护坡加固方案,从而有效提升路基稳定性。研究成果可以为相关工程施工工艺的优化、稳定性分析及加固处理提供重要参考。With the continuous expansion of highway construction scale,the construction quality of high fill subgrade is related to its stability characteristics,as well as the operation and driving safety of highways.This study is based on actual engineering projects,combined with complex geological conditions on site,and conducted using FLAC3D numerical simulation software.Research has shown that in the construction of high fill roadbeds,strict selection of fillers,accurate measurement and layout,and standardized settlement monitoring should be carried out to ensure construction quality;Numerical simulations have found significant displacement values at the top and foot of the roadbed,with a safety factor of 1.12,indicating poor stability.To this end,a mortar arch skeleton slope protection reinforcement scheme is proposed,which can effectively improve the stability of the roadbed.The research results are expected to provide important references for the optimization,stability analysis,and reinforcement treatment of related engineering construction processes.
