摘　　要：为分析再生混凝土空心砌块墙体的抗压性能,文中对轴心抗压以及偏心受压条件下再生混凝土的破坏模式、承载特性以及墙体的平面变形进行试验研究。结果表明,轴心受压作用下高厚比7.5的试件比高厚比5.4的试件开裂荷载低14.3%;破坏荷载低7.1%。偏心受压荷载作用下高厚比7.5的试件比轴心受压荷载作用下高厚比5.4的试件开裂荷载低21.4%,破坏荷载低4.1%。相同加载模式下,墙体高厚比越高,其承载荷载越低;偏心荷载作用下墙体的承载性能同样开始降低。In order to analyze the compressive performance of recycled concrete hollow block wall,the failure mode,load bearing characteris-tics and plane deformation of recycled concrete wall under axial compressive and eccentric compressive conditions were investigated.The results show that the cracking load of the specimens with height to thickness ratio 7.5 is 14.3%lower than that of the specimens with height to thick-ness ratio 5.4 under axial compression.Failure load is 7.1%lower.The cracking load and failure load of the specimens with a height to thick-ness ratio of 7.5 under eccentric compression load are 21.4%lower and 4.1%lower than those with a height to thickness ratio of 5.4 under axial compression load.Under the same loading mode,the higher the wall height to thickness ratio,the lower its load bearing capacity;The bearing performance of the wall also begins to decrease under eccentric load.
