A　Fully　Automatic　Static-dynamic　Triaxial　Shear　Apparatus　was　purchased　by　Beijing　University　of　Technology　recently.　It　has　many　good　functions　that　many　tests　can　be　done　using　the　apparatus,　including　ordinary　static　and　dynamic　triaxial　shear　test,　mixed　(radial-axial)　coupling　shear　test,　and　so　on.　It　also　can　carry　out　diversified　special　complex　stress　paths　and　graduated　loading　or　unloading　static　shear　test.　All　the　shear　process　can　be　controlled　by　computer　automatically.　In　this　paper,　the　equipment　function　of　the　Fully　Automatic　Static-dynamic　Triaxial　Shear　Apparatus　is　systematically　introduced.　Then,　some　tests　are　carried　out,　and　the　test　results　indicate　that　the　apparatus　has　good　precision　and　wide　applicability.　So,　the　soil＇s　mechanics　capability　under　complex　stress　conditions　can　be　done　using　this　apparatus.
