A　new　incremental　transfer　model　of　pile-soil　interaction　is　presented　on　the　basis　of　the　disturbed　state　concept　(DSC),　and　the　load　transmission　mechanism　is　analyzed　as　well.　According　to　the　result　obtained　with　Matlab,　the　influence　law　of　the　model　parameters　to　the　relationship　between　τ　and　s　is　analyzed.　It　show　that,　the　parameter　η　has　a　decisive　influence　on　the　pile-soil　interface　strength,　reflect　the　concentration　degree　of　the　pile-soil　interface　element　strength　distribution,　which　means　that　the　hardening,　softening　and　elastic　plastic　characteristics　of　pile-soil　interface　can　be　described　by　choosing　the　proper　parameter.　The　parameters　ξ　and　τf　have　relatively　smaller　influence　on　interface　strength,　since　the　change　in　the　parameters　only　has　effect　on　the　maximum　value　of　shaft　resistance.　The　greater　the　parameters　ξ　and　τf,　the　greater　the　extreme　value　of　the　lateral　frictional　resistance,　but　it　has　little　influence　on　the　shape　of　the　τ-s　curve.　The　parameter　k　can　affect　both　the　strength　interface　and　τ-s　curve　in　a　certain　way,　the　greater　the　peak　intensity　of　k,　the　higher　the　interface　strength,　the　smaller　the　interface　displacement　corresponding　to　the　peak　of　the　lateral　frictional　resistance.　Due　to　the　fact　that　the　theoretical　curves　agree　well　with　the　τ-s　curves　from　static　loading　test,　it　has　a　certain　guiding　significance　on　engineering　practices.　©　2017,　Science　Press.　All　right　reserved.
