Summary:The oedometer test was performed on the reconstituted soil prepared from slurry composed by Western Australian residual soil and water.An expression with dimensional consistency of intrinsic compression line which represented the relationship between void index Ivand consolidation pressure p was proposed based on a large number of oedometer tests on reconstituted soils from slurry.Four boundary conditions were used to study the parameters in the expression between Ivand pand an e-pexpression of slurry was deduced.Meanwhile some conclusions were obtained:for slurry with the initial water content of near 1.25 times liquid limit water content.The void ratio when pis 100 kPa is half of the initial void ratio;the ratio of the void ratios when pis 1000 kPa and 100 kPa is around 0.625.The ratio of the compressed void ratio from slurry state and the current void ratio has a directly proportional relationship with p/Pain the logarithmic coordinate system and the proportionality factor is about 0.34.Finally the above c
