The　construction　of　the　Three　Gorges　Project　and　the　water　impounding　of　the　reservoir　will　widely　and　continuously　affect　the　geological　environment　around　the　Three　Gorges　Area,　and　cause　a　large　number　of　geological　problems.　With　the　rise　of　water　level　of　the　reservoir,　there　will　be　340　public　dock　berths　which　belong　to　the　11　borough　or　county　harbors,　80　town　docks　and　even　more　exclusive　use　docks　of　enterprises　to　be　submerged.　So,　lots　of　ports　have　to　be　constructed　in　geologically　problematic　area　because　of　site　constraints.　Furthermore,　the　wide-range　variation　of　water　level　and　the　storage　loading　may　cause　potential　geological　problems.　The　paper,　taking　Baima　harbor　district　as　a　typical　example,　discussed　these　problems　that　affect　the　stability　and　deformation　failure　of　harbor　slopes.　On　the　basis　of　physical　modeling　experiments　and　numerical　analyses,　stability　control　measures　for　bank　slope　were　proposed.　The　numerical　simulations　indicate　that　the　deformation　failure　mechanism　of　bank　slope　under　loading　and　groundwater　seepage　is　creep-shear　failure　with　circular　sliding　plane　in　unconsolidated　debris.　The　deformation　failure　process　may　be　divided　into　two　phases:　creep　deformation　and　shear　failure.　By　back　analyses,　it　is　considered　that　the　bank　slope　of　Baima　harbor　district　is　in　a　limit　equilibrium　state　under　the　action　of　groundwater　seepage　and　variable　loadings.　With　regard　to　measures　taken　to　control　the　bank　slope　stability,　the　water　level　variation　in　the　reservoir　and　the　variable　load　in　the　harbor　were　focused　on.
