摘要：

In　order　to　get　the　tensile　strength　of　wet　screened,　three-graded,　fully-graded　concrete　the　concrete　is　considered　as　a　three-phase　composite　composed　of　matrix,　aggregate　and　the　interface　between　the　two;　the　random　aggregate　model　is　conctructed　by　using　Monte-Carlo　method.　The　bilinear　damage　evolution　model　is　adopted　to　describe　the　meso-element＇s　damage　devolution.　The　axial　tension　test　for　the　one-graded　concrete　is　studied　by　the　nonlinear　FEM;　homogenization　is　verified　in　the　axial　tension　test　for　the　two-graded　concrete;　homogenization　is　applied　in　the　axial　tension　test　for　the　fully-graded　concrete.　Furthermore,　tensile　strengths　of　fully-graded　concrete.　The　results　of　numerical　simulation　meet　experiment　results　well.
