How　to　assess　the　effect　of　stress　path　on　compression　behaviors　of　natural　soils　is　an　important　issue　in　geotechnical　engineering　practice.　A　series　of　GDS　triaxial　compression　tests　under　different　stress　paths　are　performed.　The　change　in　compression　behaviors　under　different　stress　paths　is　investigated.　It　is　found　that　the　mean　yield　effective　stress　and　the　compression　index　increase　with　the　increase　in　stress　ratio　to　the　maximum　and　then　decrease　with　the　increase　in　stress　ratio.　The　comparison　of　yield　behaviors　between　triaxial　compression　tests　and　one-dimensional　compression　tests　indicates　that　the　coefficient　of　earth　pressure　at　rest　increases　with　stress　level　during　the　yielding　of　compression,　and　becomes　constant　when　the　stress　level　is　in　the　post-yield　state.
