| 摘 要： | 针对以一个试样进行分级加载松弛试验的可行性问题,并研究堆石料的应力松弛规律,使用大型三轴仪对堆石料进行了常应变速率排水压缩试验和不同围压、不同应变水平的分级加载排水松弛试验,并建立了双曲线应力松弛方程.结果表明应力松弛阶段对后续常应变速率加载的应力应变关系趋势基本无影响,以一个试样分级加载方式进行松弛试验是可行的.在应...

| Abstract: | In order to analyze the feasibility of a single specimen used for step-loaded relaxation tests and study the time dependent stress relaxation properties of rockfill,two types of the drained triaxial compression tests were carried out with large-scale triaxial apparatus for rockfill.One was the constant-strain-rate triaxial compression tests,and the other was the step-loaded drained triaxial relaxation tests under different confined pressures and strain levels.A hyperbolic function was presented to simulate ... |
