  :基于深入调查国内外台背差异沉降的控制标准,通过对某高速公路用煤矸石作为台背回填材料的研究,文章采用ANSYS有限元软件计算该高速公路不同粗颗粒含量、压实度和煤矸石台背回填差异沉降值,确定了煤矸石路基台背回填的合理颗粒级配及压实度,评价了煤矸石路基作为台背回填料的性能,为设计及施工提供参考。

AbstractBased on an extensive survey analysis on domestic and foreign abutment differential settlement control standardsstudy on the coal gangue as an abutment backfill. The paper usesd the finite element method compute different coarse particle contentcompaction degree and differential settlement value of coal gangue in highway. which determined appropriate composition degreeevaluated the performance of coal gangue subgradeprovided guidance for the design and construction.
