The failure mechanism of fly ash ceramsite lightweight aggregate concrete under triaxial compression was investigated via conventional triaxial tests at different strength grades and lateral confining pressures. The failure morphology and stress-strain curve of fly ash ceramsite concrete specimens under triaxial compression were analyzed, and the failure mechanism was revealed. The results show that under triaxial compression, the fly ash ceramsite concrete has three failure phenomena as the applied confining pressure increases, i.e., vertical splitting failure, oblique shear failure, and no obvious cracks. There exists a platform flow plastic phenomenon in the full strain curve with the increase of confining pressure. The triaxial compression of fly ash ceramsite concrete can be properly described by an established general formula for the Mohr-Coulomb, octahedral shear stress failure criterion and the Rendulic plane failure criterion.

为研究粉煤灰陶粒轻骨料混凝土的三轴受压破坏机理，以强度等级、侧向围压为变化参数，共设计78个试件进行常规三轴试验。观察分析了三轴受压下粉煤灰陶粒混凝土试件的破坏形态和应力-应变全曲线，揭示了其破坏机理。结果表明：三轴受压下，粉煤灰陶粒混凝土随围压的增大出现竖向劈裂破坏、斜向剪切破坏、无明显裂缝3种破坏现象，并呈现良好的延性性能；应力-应变全曲线随围压的增大存在明显平台流塑现象，围压σw大于12 MPa以后，曲线基本不出现下降段；建立的莫尔-库伦、八面体剪应力破坏准则及Rendulic平面破坏准则通用式，均能较好反映粉煤灰陶粒混凝土的三轴受压状态。

为研究粉煤灰陶粒轻骨料混凝土的三轴受压破坏机理，以强度等级、侧向围压为变化参数，共设计78个试件进行常规三轴试验。观察分析了三轴受压下粉煤灰陶粒混凝土试件的破坏形态和应力-应变全曲线，揭示了其破坏机理。结果表明：三轴受压下，粉煤灰陶粒混凝土随围压的增大出现竖向劈裂破坏、斜向剪切破坏、无明显裂缝3种破坏现象，并呈现良好的延性性能；应力-应变全曲线随围压的增大存在明显平台流塑现象，围压σw大于12 MPa以后，曲线基本不出现下降段；建立的莫尔-库伦、八面体剪应力破坏准则及Rendulic平面破坏准则通用式，均能较好反映粉煤灰陶粒混凝土的三轴受压状态。

The failure mechanism of fly ash ceramsite lightweight aggregate concrete under triaxial compression was investigated via conventional triaxial tests at different strength grades and lateral confining pressures. The failure morphology and stress-strain curve of fly ash ceramsite concrete specimens under triaxial compression were analyzed, and the failure mechanism was revealed. The results show that under triaxial compression, the fly ash ceramsite concrete has three failure phenomena as the applied confining pressure increases, i.e., vertical splitting failure, oblique shear failure, and no obvious cracks. There exists a platform flow plastic phenomenon in the full strain curve with the increase of confining pressure. The triaxial compression of fly ash ceramsite concrete can be properly described by an established general formula for the Mohr-Coulomb, octahedral shear stress failure criterion and the Rendulic plane failure criterion.
