摘要: Abstract The paper presents an experimental study on the influence of grain size distribution curve dynamic soil properties. More than 160 resonant column tests with additional P-wave measurements have been performed 27 different curves a quartz sand. While small-strain shear modulus Gmax has discussed by Wichtmann and Triantafyllidis [1] present focusses velocity vP, constrained elastic Mmax Poisson's ratio ν . It is demonstrated that while vP do not significantly depend mean d50 in investigated range, they decrease increasing coefficient uniformity Cu=d60/d10 curve. does also but increases Cu. An empirical formula similar to Hardin's equation developed for Mmax, considering predicts quite well data.
