| 摘 要： | 在前期大量单轴试验的基础上,对超贫胶结材料试件进行了三轴试验,得到不同胶凝材料用量、不同围压下的应力-应变曲线,分析了胶凝材料用量及围压对应力-应变曲线的影响,探讨了不同试验条件下试件的强度、体积变形规律以及残余强度等,为超贫胶结材料本构模型的建立奠定了基础。

| Abstract: | Based on great deal of uniaxial tests in former stage,triaxial tests were performed on over lean cemented material specimens,and the stress-strain curve for the specimens with different amounts of cementing material under different confining pressures were obtained.The influences of dosage of cementing material and confining pressure on the stress-strain curve were analyzed,and the strength,the law of volume variation,and the residual strength of over lean cemented material under different test conditions were also discussed.The present study provides a basis for establishment of the constitutive model for over lean cemented material. |

| Keywords: | over lean cemented material stress-strain relationship triaxial test |
