摘要：

Clay　silt　in　some　section　of　Beijing　subway　No.10　is　used　as　reconstituted　way,　multifunctional　triaxial　equipment　of　GDS　is　used　to　do　CD　and　CU　triaxial　test,　and　then　basic　intensity　index,　stress-strain　relation　and　model　parameters　were　got.　The　Mohr-Coulomb　model,　Druker-Prager　model　and　Modifed　Cam-Clay　model　of　ABAQUS　are　used　to　do　numerical　simulation,　including　failure　process　of　sample　and　effect　of　dilation　to　sample　failure.　The　results　show　that　Modifed　Cam-Clay　Model　can＇t　be　used　to　simulate　dilation,　Mohr-Coulomb　model　and　Druker-Prager　model　consider　dilation　excessively.　The　failure　mode　of　model　with　dilation　form　shear　band　firstly　in　drained　condition,　while　the　failure　mode　of　model　without　dilation　form　shear　band　firstly　in　undrained　condition.
