A　two-phase　turbulent　model　of　Bingham　fluid　and　particles　is　presented　according　to　dense　liquid-solid　two-phase　turbulent　equations　and　power　law　fluid　constitutive　equation.　A　computer　program　is　developed,　which　provides　the　theoretical　basis　for　numerical　computation.　With　inter　phase　slip　algorithm　revised　(IPSAR),　numerical　computation　is　performed　for　the　two-phase　turbulent　flow　of　Bingham　fluid　and　particles　in　pipe.　The　results　show　that　the　velocity　distribution　of　particle　phase　is　flat　and　higher　near　wall　than　the　velocity　of　power　law　fluid,　that　the　mainstream　velocity　of　both　phases　increases　with　increase　of　flow　index,　that　the　turbulent　kinetic　energy　of　power　law　fluid　has　a　tendency　to　increase,　and　that　the　particle　volume　fraction　appears　a　tendency　to　reduce.　So　yield　stress　has　an　important　influence　on　turbulent　flow.
