摘　　要：对两组N式砌块砌体进行了受压性能试验研究,了解了N式砌块的破坏形态及破坏机理。试验结果表明,N式砌块砌体的抗压强度平均值较普通混凝土小型砌块抗压强度平均值提高了30%～52%。分析表明,其强度提高的主要原因是N式砌块砌体实现了孔、肋对齐。给出了N式砌块砌体抗压强度平均值和弹性模量值的计算公式,与试验结果吻合良好。Based on two sets of specimens, the compressive behaviors of N-type block masonry were investigated. Through these tests, the failure mode and the failure mechanism were studied. Test results show that the average compressive strength of N-type block masonry is increased by 30% - 52% as compared to the common concrete masonry. The main reason for the strength rising is the full-alignment of web-shells in N-type block masonry prisms. Recommended formulas for calculating average compressive strength and modulus of elasticity is presented and the calculated results by the formulas are in good agreement with the test results.
