为研究配植物筋砌块砌体轴心抗压性能,考虑两种砌块强度等级、两种砂浆强度等级及三种植物筋配筋率的影响,制作7组配植物筋砌块砌体进行轴心抗压试验,研究其破坏机理和轴心抗压强度,对比分析不同因素对配植物筋砌体其抗压强度的影响；运用ABAQUS有限元软件对种配植物筋砌体轴心抗压试验进行数值模拟,结合试验研究和数值模拟结果,推导不同工况组合的配植物筋砌块砌体轴心抗压强度值。研究结果表明：配置植物筋对砌体灰缝处裂缝发展有明显阻碍作用；在其他工况不变的情况下,采用B07级加气块比B06级加气块砌体的抗压强度平均提高25.6%,M7.5级砂浆比M5级砂浆砌筑砌体抗压强度平均提高12.2%,每层配植物筋与隔层配植物筋砌体较不配筋砌体抗压强度分别提高8.52%和2.84%；引入的修正系数ψ取0.7时拟合得到的配植物筋砌块砌体抗压强度计算值与试验值吻合较好。

In order to study the axial compressive properties of the block masonry reinforced with plants, considering the impact of two strengths, two mortar strength grades and different reinforce-ment ratios of three plants and preparing 7 groups of block masonry reinforced with plants, the axial compressive tests were conducted. The failure mechanism, ultimate load and axial compressive strength were analyzed, and a comparative analysis on the impact of different factors on the compres-sive strength of the masonry was carried out. The finite element software ABAQUS was used to nu-merically simulate the axial compressive test of the masonry, and the experimental and numerical re-sults are combined to derive the axial compressive strength values of the masonry under different combinations of working conditions. The results show that plant reinforcement for the block masonry obviously prevents the growth of ash seam. When other conditions are the same, the compressive strength of the aerated block B07 is averagely 25. 6% higher than that of B06 , and the compressive strength of mortar M7 . 5 is averagely 12. 2% higher than that of M5 . The compressive strengths of the masonries reinforced with plant in each layer and in every two layers are 8. 52% and 2. 84%higher than that of the unreinforced masonry. When the correction coefficient is 0. 7, the calculated compressive strength accords well with the experimental value.
