摘要
通过对路基边坡破坏机理分析,总结出高填方路基的特点和薄弱部位。以山西太原某公路斜坡高填方黄土路基为例,对其采取了系统的加固技术,即地表接触面开挖台阶、填土内部使用土工格栅、坡脚处设置挡墙和铲子状沟槽、表面钢筋混凝土格栅加固相结合的方式处理斜坡高填方路基。结果表明,采取这种综合加固措施能有效提高路基稳定性。
Based on the analysis of the embankment slope failure mechanism, the paper summed up the characteristics of high subgrade and weak parts. Taking the high filling slope subgrade in Taiyuan for example, the paper put forward the systematic reinforcement technology, that is excavating steps at the contact surface; using geogrid as reinforced material ; using the retaining wall and shovel - shaped groove at the foot of the slope ; surface reinforcement concrete reinforced by a combination of high fill embankment slope. The results show the comprehensive strengthening can aftereffect improve the stability of embankment.
