| 摘 要： | 使用新研制的大型单剪仪,对粗粒土的颗粒破碎及粗粒土一结构接触面进行了系统的试验研究,分析了试验中影响颗粒破碎的主要因素及颗粒破碎对粗粒土一结构接触面应力应变特性的影响.试验结果表明,颗粒破碎率随着法向应力的增大而增大,颗粒破碎受剪应力大小的影响程度随着法向应力的增大而减小.

| Abstract: | The newly-developed large-scale simple shear apparatus was employed to systematically study the particle breakage of coarse-grained soil and the interface between the coarse-grained soil and other structures.The main factors affecting the particle breakage and the effects of the particle breakage on the stress-strain behaviors of the coarse-grained soil-structure interface were analyzed.The test results show that the particle breakage rate increases with the increase of the normal stress and the effect of t... |
