| Abstract: | Broadly graded coarse material is widely used in earth-rock dams.However,the research of seepage test method for this material is still insufficient.Research on test methods of broadly graded coarse material is reviewed. Problems occurring in test specifications are pointed out.Three main factors that influence the seepage test result are apparatus size effect,wall effect and air bubbles in water.A scheme to study these problems is suggested. |
