摘　　要：以路基浅层处理为研究对象,通过室内模型试验对土工格栅加筋体的局部应力—应变分布以及剪切破坏状况进行了研究,并得出科学结论,从而对加筋砂土的变形破坏以及补强材料的加固机理有了更加全面深入的认识。Taking roadbed shallow layer treatment as the research object, through the indoor model test, this paper researched the local stress- strain distribution and shear failure condition of geogrid reinforced, and draw scientific conclusion, so as to have a more comprehensive and in- depth understanding to deformation failures and reinforcement mechanism of reinforced sand soil.

关 键 词：土工格栅 加筋砂土 平面应变压缩 补强材料
