Abstract：In order to explore the effective method of solidifying the red soil layer,this study used clay solidification agent and cement soil as the solidification agent. By compaction test,unconfined compressive strength test,the stability of immersion test after solidification,measure and analyze the influence rule of the mixture of different dosage in the characteristics of compaction, the characteristics after soaking in the water,water absorption rate,compressive strength and softening coefficient after soaking in the water,etc. The test results show that the water stability and compressive strength of specimen with mixture are significantly higher than red soil layer and red soil layer with clay solidification agent or cement. The specimen with mixture can reach 2.3 MPa and can reach more than 95％ of the maximum intensity after 7 curing ages,its strength loss after soaking in the water is less than 0.5％. The test results show that the mixture of clay solidification agent and cement used in this experiment has played a significant solidification effect.
