Abstract

Abstract

Through laboratory tests on sandy pebble soil by using the dynamic triaxial test,researches of saturated sandy pebble soil have been done.It was analyzed the rule of the dynamic characters of sandy pebble soil under different confining pressure,consolidation ratio and vibration frequency.The result shows that the dynamic modulus of sandy pebble soil reduces nonlinearly with the accretion of dynamic strain,but increases with consolidation ratio,and affected little by the vibration frequency.In addition,the research also makes it clear that damping ratio markedly rises with the augmentation of dynamic strain,and falls as the enhance of confining pressure or consolidation ratio.
