The　consolidation　state　of　soft　soil　is　of　significance　for　evaluation　of　deformation　and　strength　of　foundation　soil.　The　consolidation　state　of　soft　soil　in　the　coastal　area　of　Fujian　Province　is　differentiated　by　static　cone　sounding.　For　the　normal　consolidation　state,　the　fitting　beeline　of　static　cone　sounding　of　soft　soil　between　cone　resistance　and　test　depth　intersects　the　x-coordinate　at　the　origin　approximately;　for　the　overconsolidation　state,　intersects　the　positive　x　coordinate;　and　for　the　underconsolidation　state,　intersects　the　negative　x　coordinate.　The　consolidation　state　of　soft　soil　can　be　differentiated　by　the　intercept　of　the　line.　The　consolidation　state　of　soft　soil,　tested　by　in-situ　static　cone　sounding,　fits　the　actual　condition　of　soft　soil;　and　the　method　can　be　used　for　the　evaluation　of　the　consolidation　state　of　soft　soil.
