Based　on　a　series　of　consolidation　tests　for　undisturbed　samples　in　Fuzhou,　the　influence　of　consolidation　pressure,　load　ratios,　overload　pre-pressure　and　overload　pre-pressure　duration　on　secondary　consolidation　properties　was　studied.　The　results　show　that　the　secondary　consolidation　coefficient　Ca　correspondingly　increases　or　decreases　with　the　increase　or　decrease　of　the　loading　ratio.　Along　with　the　increase　of　consolidation　pressure,　the　secondary　consolidation　coefficient　for　normally　consolidated　soil　increases　at　first　and　then　decreases,　but　it　remains　increasing　for　over-consolidated　soft　soils.　The　decrease　of　secondary　consolidation　coefficient　is　related　not　only　to　the　over-consolidation　ratio　but　also　to　overload　pre-pressure　duration.　For　Fuzhou　soft　soil,　the　ratio　of　secondary　consolidation　coefficient　Ca　and　compression　index　Cc　is　0.029　to　0.052.　©,　2014,　Central　South　University　of　Technology.　All　right　reserved.
