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。
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-straln 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.
