通过一系列不同小主应力比和中主应力比的真三轴压缩试验，系统研究了模拟密实堆石料的强度和塑性特性。结果表明，中间主应力比对模拟堆石料的临界状态摩擦角、峰值状态摩擦角和最大粘性有很大影响。临界状态和峰值状态的摩擦角在一个给定的围压先增加，然后减少与中间主应力比的增加。在给定的中间主应力比下，小主应力的增加导致临界状态和峰值状态摩擦角的减小。随着小主应力或中主应力比的增大，最大剪切强度减小。中主应力比的大小对两者的关系有显著影响。
AbstractThe strength and dilatancy behaviors of modeled dense rockfill material were systematically investigated through a series of true triaxial compression tests at different minor principal stress and intermediate principal stress ratios. It was found that the intermediate principal stress ratio had great influence on the critical-state friction angle, peak-state friction angle, and maximum dilatancy of the modeled rockfill material. Both the critical-state and peak-state friction angles at a given confining pressure first increased and then decreased with an increase in the intermediate principal stress ratio. An increase in the minor principal stress led to a decrease in both the critical-state and peak-state friction angles at a given intermediate principal stress ratio. The maximum dilatancy decreased with an increase in the minor principal stress or the intermediate principal stress ratio. It was also found that the intermediate principal stress ratio significantly affected the relationship betwe...
