Comparative experiment research on dynamic deformation behaviors of lightweight sand-EPS beads soil (LSES) with sand is taken with mixing proportions determined by dry density. Test results indicate that Ed (dynamic elastic modulus) of LSES and sands both decrease with the increase of strain; and Ed of LSES with different contents of cement and EPS beads are all larger than that of sands. Ed of LSES and sands both increase with the increase of ?c (confining pressure)
but the influence of ?c on LSES is more notable. D (equivalent damping ratio) of LSES and sands both increase with the increase of strain. D of LSES approximates to that of sands when content of cement is low
and D of LSES is smaller with higher content of cement. D of LSES and sands both decrease with the increase of ?c
