Advanced Materials Research, 2011 A series of dynamic triaxial tests which used saturated samples of three different particle size distribution anti-filter materials in high earth-rock dams have been investigated for the development of dynamic pore-water pressure. The experimental results show that the relationship between μd/σ'm and N/Nf in the same consolidation condition are unitary
