Paper Title:
Experimental Study on Development Characteristics of Dynamic Pore-Water Pressure of Anti-Filter Material in High Earth-Rock Dam
  Abstract

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 if we applied different dynamic stress to the same particle size distribution anti-filter material. Besides, if N/Nf <0.6, the value of μd/σ'm increases quickly. The increase rate of μd/σ'm will be slower if N/Nf≥0.6. When the consolidation stress ratio is invariant, the change of ambient pressure has no effect on relationship between μd/σ'm and N/Nf. When the gradation and ambient pressure of anti-filter material are changeless, the change of consolidation stress ratio has obvious effects on relationship between μd/σ'm and N/Nf. When the value of consolidation stress ratio is increase, the number of dynamic pore-water pressure ratio obviously decrease. When the consolidation condition of anti-filter material is changeless, the change of anti-filter material’s grade doesn’t have obvious effects on the relationship between μd/σ'm and N/Nf.
