Along　with　the　development　of　virtual　reality　technology,　simulation　system　as　a　new　perspective　of　management　methods　and　technical　means　in　the　progress　of　the　project　management,　plays　an　increasingly　important　role.　This　paper　discussed　the　development　of　applications　based　on　Qt　framework　and　the　OSG　Engineer　application　programming　interface　pouring　simulation　system　development　methods,　and　realized　a　concrete　dam　pouring　process　of　visual　simulation.　At　the　technical　level,　we　proposed　that　the　mode　of　the　dam　for　a　certain　period　could　be　created　by　cutting　a　whole　3D　dam　model,　avoiding　creating　it　manually.　The　data　was　collected　to　generate　corresponding　pouring.　The　two-dimensional　visualization　of　the　same　train　of　thought　had　the　dynamic　simulation　pouring　situation　at　the　same　time.　Temperature,　stress　field　scattered　data　points　for　the　network　reconstruction　Georgia,　integrated　with　the　two-dimensional　simulation　together.
