Correlation between inter-granular void ratio and cone tip resistance of loose silty sand

摘要

The purpose of this research is to evaluate the correlation between inter-granular void ratio and cone tip resistance in silty sand. Twenty-seven cone penetration tests are performed in saturated silty sand samples with several different silt contents ranging from 10 to 50 percent. It is shown that, as the silt content increases, the cone tip resistance decreases. In high percent of silt (30 -50 %), the cone tip resistance decreases more gently compared with low percent of silt (0 - 30%).
