In　coastal　areas,　concrete　structures　are　not　only　subjected　to　environmental　attacks　(e.　g.　the　penetration　and　diffusion　of　chloride　ions)　but　also　the　mechanical　loadings　including　wind　loads,　vehicle　loads,　wave　loads　and　even　seismic　loads.　The　external　mechanical　stresses　may　change　the　micro-/meso-structure　of　concrete,　and　even　cause　new　micro-cracks　to　be　generated.　This　leads　to　the　change　of　the　penetration　and　diffusion　boundary　conditions　of　chloride　ions,　and　finally　the　change　of　the　permeability　and　diffusivity　of　chloride　ions.　From　the　viewpoints　of　lower　and　higher　mechanical　stress　levels,　the　available　experimental,　theoretical　and　numerical　efforts　to　study　the　effects　of　external　loadings　on　chloride　ions　penetration　and　diffusion　into　concrete　were　introduced.　One　can　note　that　the　available　efforts　mainly　focus　on　experimental　tests　rather　than　theoretical　analysis.　The　concrete　studied　is　mostly　saturated　instead　of　unsaturated.　Moreover,　the　analysis　is　conducted　based　on　the　macro-scale　model　for　the　most　part,　without　considering　the　meso-scale　heterogeneity　of　concrete.　Finally,　it　is　suggested　that　experiments　on　chloride　penetration　and　diffusion　into　concrete　in　the　complex　environment　and　complex　stress　state　should　be　conducted.　A　model　that　unifies　the　influences　of　lower　stress　level　and　higher　stress　level　needs　to　be　established.　The　multi-field　and　multi-scale　analysis　of　chloride　diffusion　in　concrete　under　the　coupling　effects　of　mechanics　and　environment　should　be　carried　out　in　future.　©　2016,　Science　Press.　All　right　reserved.
