摘 要:使用DYS-2500高温高压岩石三轴试验机对钢纤维再生混凝土圆柱体进行了单轴压缩和常规三轴压缩试验研究。结果表明,钢纤维再生混凝土在单轴压缩和三轴压缩下的破坏形态有所差别;同一围压下,钢纤维再生混凝土随着钢纤维掺量的增加,试件能承受的主压应力及轴向应变也相应增加,且围压下的应力-应变曲线走势大体一致;相同掺量钢纤维再生混凝土,随着围压值的提高,其承受的主压应力、轴向应变也相应提高;围压15MPa时,钢纤维再生混凝土的峰值应力约是单轴压缩下峰值应力的3.08~4.13倍;同一围压下的纤维再生混凝土,钢纤维掺量2%的峰值应力约是普通再生混凝土峰值应力的1.15~1.54倍;围压15MPa时钢纤维再生混凝土的峰值应变比0MPa时的峰值应变增加了5.98~6.76倍;同一围压下的再生混凝土,钢纤维掺量2%的峰值应变约是普通再生混凝土峰值应变的1.22~1.52倍。 Abstract: DYS-2500 high temperature and high pressure rock triaxial testing machine is used to carry out the uniaxial pressure and conventional triaxial compression test of steel fiber recycled concrete cylinder. The test results show that the failure pattern of steel fiber recycled concrete under uniaxial compression and triaxial compression test is different. Under the same confining pressure, the main compressive stress and axial strain of fiber regenerated concrete increased with the increase of steel fiber parameters. The stress-strain curve of the confining pressure is generally consistent. With the increase of the confining pressure value, the axial strain of the main compressive stress of the same steel fiber reinforced concrete is improved accordingly. The peak stress of mixed fiber recycled concrete was 3.08~4.13 times of the peak stress of single axial pressure when confining pressure of 15MPa. The peak stress of two percent of the steel fiber parameters is about 1.15~1.54 times the peak stress of the recycled concrete. The peak strain of mixed fiber regenerated concrete at 15MPa is 5.98~6.76 times higher than that in 0MPa. The peak strain of 2% of steel fiber parameter is 1.22~1.52 times of the peak strain of recycled concrete.

Abstract:  DYS-2500 high temperature and high pressure rock triaxial testing machine is used to carry out the uniaxial pressure and conventional triaxial compression test of steel fiber recycled concrete cylinder. The test results show that the failure pattern of steel fiber recycled concrete under uniaxial compression and triaxial compression test is different. Under the same confining pressure, the main compressive stress and axial strain of fiber regenerated concrete increased with the increase of steel fiber parameters. The stress-strain curve of the confining pressure is generally consistent. With the increase of the confining pressure value, the axial strain of the main compressive stress of the same steel fiber reinforced concrete is improved accordingly. The peak stress of mixed fiber recycled concrete was 3.08~4.13 times of the peak stress of single axial pressure when confining pressure of 15MPa. The peak stress of two percent of the steel fiber parameters is about 1.15~1.54 times the peak stress of the recycled concrete. The peak strain of mixed fiber regenerated concrete at 15MPa is 5.98~6.76 times higher than that in 0MPa. The peak strain of 2% of steel fiber parameter is 1.22~1.52 times of the peak strain of recycled concrete.
