The　difficulty　in　measuring　the　permeability　of　clays　with　enough　accuracy　enhances　the　importance　of　quantitatively　predicting　the　permeability　with　simple　physical　parameters.　This　study　collects　23　groups　of　data　of　permeability　of　remolded　clays　considering　the　effect　of　oedometer　consolidation　pressure.　The　investigated　clays　cover　a　wide　range　of　liquid　limits,　varying　from　40%　to　300%.　Based　on　the　data　of　permeability,　it　is　found　that　the　logarithm　of　permeability　coefficient　changes　with　the　void　ratio　in　the　exponential　form,　other　than　in　the　linear　relationship,　especially　when　the　volumetric　strain　reaches　the　level　of　20%.　The　controlling　factors　of　the　permeability　coefficient　of　clays　are　analysed　by　multiple　regression　analysis.　A　simple　method　is　also　proposed　for　predicting　the　permeability　coefficient,　which　can　be　applied　to　remolded　clays　with　wide　ranges　of　liquid　limit　and　void　ratio.
