Based　on　one　dimensional　consolidation　tests　on　soft　soil　samples,　the　influence　of　repeated　cyclic　loading　on　the　secondary　consolidation　properties　was　investigated　considering　the　upper　soil　layers＇　stress.　The　results　show　that　during　the　loading　cyclic　stage,　the　secondary　consolidation　coefficient　of　soft　soil　Ca　decreases　with　the　increase　of　the　largest　preloading　pressure.　Ca　also　decreases　significantly　with　the　increase　of　the　loading　cycle　number,　while　it　decreases　slowly　after　20　cycles.　The　larger　the　cyclic　loading　is,　the　greater　the　Ca　is,　and　it　decreases　more　quickly.　After　35　cycles,　Ca　increases　with　the　increase　of　the　reloading　pressure　p1,　and　there　is　a　linear　relationship　between　Ca　and　lg　p1.　Ca　also　increases　with　the　increase　of　the　largest　preloading　pressure　and　its　lasting　time.　©　2016,　Central　South　University　Press.　All　right　reserved.
