Abstract：Using the area of Chongqing soil as raw material,rice straw and slag as modified materials,in accordance with the different dosage of modified materials to produce modified raw soil specimens of different ratio,the shear strength,compressive strength,thermal conductivity are tested. The experimental data showed that the appropriate amount of straw or slag can be adjust-ed to increase the shear strength of 50%~100%,92.7%~123.0%,the maximum compressive strength increased by 23.7% and 49.6%,respectively,and thermal conductivity decreased by about 5%. The optimum ratio of straw is 0.25%~0.50%,the best propor-tion of slag is 8%~10%.
