Generally, the strength of soil increases as the water content decreases. The detailed information on the relation is unknown when the water content is lower than 20%. The purpose of this study is to make clear the relation between the water content arid strength of muddy soil mixed with coal fly ash, in order to obtain the best water content. The results obtained are as follows. (1) When the muddy soil mixes with coal fly ash or dries naturally in the room, its water content decreases and the maximum strength comes in 20-25% of water content. Then the best water content of treated soil is 20-25 %. (2) The fluidized bed combustion coal fly ash has effect of increasing strength of treated soil more than the pulverized coal fly ash. (3) The water content decreases and strength increases with the ageing of treated soil. (4) The water content of treated soil under the best water content increases extremely and the strength decreases nearly zero when the soil is submerged.
