| 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。

| Abstract: | 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. |
