Abstract：In order to explore the static characteristics of medium sand class B group subgrade soil, four kinds of medium sand class B group soil with different fine particle contents were prepared with the medium sand and silty clay based on understanding the physical properties of subgrade soil. The influence of confining pressure and fine particle content on the stress-strain relationship and static strength of the testing soil was studied with the conventional triaxial compression test. The results show that at the same fine particle content, the stress-strain curve of the sample significantly increases with increasing the confining pressure. At the same strain value, the stress difference is large, and the stress difference on the 150 kPa curve is the most obvious. At the same confining pressure, the fine particle content has no obvious influence on the stress-strain curve. When the fine particle content is less than 30%, the trend of stress-strain curve is almost unanimously, and the stress increases with increasing the strain.
