Gravelly　soil,　a　mixture　of　clay　and　gravel,　has　been　widely　used　as　a　core　material　of　high　earth　core　rock　fill　dams.　The　triaxial　consolidated　drained　(CD)　test　for　gravelly　soil　is　time-consuming,　especially　for　larger　scale　test　samples　because　of　its　low　permeability　caused　by　the　high　content　of　clay.　This　study　presents　a　quick　triaxial　consolidated　drained　(QCD)　test,　which　can　greatly　accelerate　the　CD　test　on　gravelly　soil.　In　the　QCD　test,　the　traditional　cylindrical　specimen　was　modified　to　a　sand-core　cylindrical　specimen　containing　a　hollow　cylindrical　specimen,　and　the　sand　column　filled　in　the　central　hollow.　As　a　result,　the　sand　column　in　the　center　of　the　specimen　greatly　accelerates　the　water　drainage　of　the　specimen,　and　both　the　consolidation　stage　and　the　shear　stage　of　the　test　can　be　finished　quickly.　Based　on　gravelly　soil,　the　comparative　tests,　including　CD　tests　and　QCD　tests,　are　performed.　It　is　concluded　that　the　QCD　tests　can　be　conducted　more　rapidly　than　CD　tests,　and　the　test　results　of　QCD　tests,　for　both　stress-strain　curves　and　the　parameters　of　the　Duncan-Chang　model,　are　basically　identical　with　that　of　the　CD　tests.　The　QCD　test　can　greatly　shorten　the　studying　time　on　gravelly　soil,　i.　e.,　the　core　material　of　earth　core　rock　fill　dams,　thus　speeding　up　the　future　design　of　dams.
