THE DYNAMIC CHARACTERISTICS OF SANDY PEBBLE SOIL

摘要：

The dynamic tri-axial test was adopted by the authors to analyze the dynamic strength and modulus of saturated sandy pebble soil whose water proportion and dry density are stable,and respectively to study the variation law of dynamic strength and modulus under diversified confining pressure,concretionary ratio and vibration frequency.The result shows that the dynamic modulus of sandy pebble soil reduces nonlinearity with the accretion of dynamic strain,but increases with concretionary ratio,and was affected little by the vibration frequency.In addition,the research also makes clear that damping ratio markedly rises with the augmentation of dynamic strain,and falls as the enhancement of confining pressure or concretionary ratio.
