加筋土陡边坡防护施工技术在山区高速公路中的应用

Application of Reinforced Soil Steep Slope Protection Construction Technology in Mountainous Expressway

山区高速公路高填方路基边坡具有较大放坡面积,但是受到征地和地形限制影响下,边坡处采取码放麻袋和单向土工格栅反爆麻袋的处理方案,使得路基常规坡度由1:1.5变成为1:0.5。将土工格栅增设在高路堤填土中,可以起到嵌镶土体的作用,从而使得土体的抗剪能力增加,避免土体向外位移。论文结合某高速公路施工项目,简要介绍加筋土陡边坡路基的施工,从而概括出相应的处理施工质量问题的措施。

The mountainous area highway high embankment slope with large slope area, but by the land expropriation and the limitation of terrain under the influence of slope treatment schemes take stacked sacks and unidirectional geogrid anti explosion sack, the subgrade slope from conventional 1：1.5 into 1：0.5. The geogrid is in high embankment fill, can play the role of mosaic soil and the soil, the shear capacity increases, avoid soil displacement. This paper will combine a highway construction project, a brief introduction of reinforced soil slope roadbed construction, thus summed up the corresponding measures to deal with the construction quality problems.
