摘要
利用作者研制的混凝土三轴试验系统，通过１８４块钢纤维混凝土试块在三向受压、两压一拉、两拉一压及三拉应力状态下试验研究，系统探讨了三向受力状态下钢纤维混凝土的变形特性，分析了应力一应变关系曲线的特点以及纤维含量和中间应力对峰值应变的影响，讨论了三向应力状态下的体积应变规律．
specimens of steel fibre reinforced concrete under triaxial stresses are studied experimentally with the triaxial apparatus designed by the authors.The emphasis is put on the study of the characteristics of deformation. The stress ratiossubjected to the specimens include triaxial compression,biaxial compressionuniaxial tension, biaxial tension-uniaxial compression and triaxial tension. Thecharacteristics of the stress-strain relationship and the influences of steel fibre content and intermediate principal stress on the peak strain are analy--sed.The stress-volume strain relationships of steel fibre reinforced concrete under triakial stresses are discussed.
