摘要
利用自制的三轴试验装置，对国内外较少进行的混凝土在两压一拉状态下的变形 和强度进行了试验研究，给出了在各种应力组合下混凝土的应力－应变关系曲线及极 限强度。在分析试验资料的基础上，建议了一个用八面体应力表述的适于混凝土在压 拉状态的强度准则。
Experimental studies on the deformation and strength of concrete unde combined biaxial compression and uniaxial tension are carried out with the triaxial test apparatus designed by the authors. The stress-strain relationship, curves and ultimate strength of concrete under different stress ratios are given. Based on the test data, a strength criterion' which is expressed in terms of octa- hedral stresses and is suitable for concrete under combined biaxial or uniaxial compression and uniaxial tension is proposed.
