摘　　要：根据土工格栅加固陡坡路堤的加固形式,采用室内小比尺离心模型试验模拟并分析了2种不同陡坡路堤边坡坡比、2种不同路堤填料干密度以及7种不同工况条件下陡坡路堤的变形规律。试验结果表明,采用土工格栅加筋能大大提高陡坡路堤的稳定性和承载能力,具有较好的工程应用价值。According to reinforcement measure of reinforcing geogrids applied in steep slope embankment, indoor small scale centrifugal model test is adopted to simulate and analyze the rule of deformation of steep slope embankment under 2 different embankment slope ratios, 2 different embankment backfill dry densities and 7 different construction conditions. Test results show the application of reinforcing geogrids may greatly meliorate the stability and bearing ability of steep slope embankment, and it has relatively good engineering application value.
