摘要
Based on the corresponding relationship between moisture content and matric suction, an innovative model to predict dynamic resilient modulus of subgrade based on matric suction was established, which integrate the influence of stress state (confining pressure and circular deviator stress) and moisture condition (matric suction). The results indicate that values parameters of SWCC are distinct for each specimens, MR values increases with the increasing confining pressure, matric suction and compaction degree, and the circular deviator stress and moisture content decrease. Comparing to silty soil, the dynamic resilient modulus of clay is more sensitive to stress state and moisture content.
