【摘要】 本文介绍采用南京自动化研究所研制的GZ=1型共振柱仪,研究在不同密度、不同侧限压力及受均等和不均等固结应力比条件下对饱和砂样剪切模量和阻尼比的影响。指出剪切模量随试样密度,侧限压力的增加而升高。对不均等固结应力可用平均应力法归一到均等应力的模量线上。更多还原

【Abstract】 This paper deals with the effects of different density, lateral pressure, as well as uniform and non-uniform consolidation stress ratios of saturated sand on its shear modulus and damping ratio when the sand sample is tested with GZ-1 Resonant-Column Test Apparatus developed by Nanjing Automation Research Institute. The experimental results showed that with increasing sample density and lateral pressure, the shear modulus increased, and by average stress method, the non-uniform consolidation stress could be normalized to the modulus line of uniform stress.更多还原
