摘　　要：近年来,再生混凝土砌块砌体已成为研究的重点,但在再生混凝土横孔砌块砌体方面的研究较少。文中通过对3片再生混凝土橫孔砌块墙体的轴心受压试验以及3片再生混凝土橫孔砌块墙体的偏心受压试验研究,得到了再生混凝土横孔空心砌块墙体在均匀荷载作用下的破坏形态、受压工作机理及变形特征等。根据我国相关规范,结合试验结果,文中得到了再生混凝土横孔砌块墙体的抗压强度计算方法。通过研究解决了再生混凝土横孔砌块墙体强度设计问题,为再生混凝土横孔砌块墙体在竖向荷载作用下的有限元分析和内力分析提供了重要依据。In the past years,recycled concrete block masonry has become a research hotspot,but in recycled concrete transverse hole block masonry research is less.Through the axial compression test of 3 specimens and the eccentric compression test of 3 specimens of recycled concrete transverse hole block wall,the failure form,deformation characteristics and compression working mechanism are obtained.Based on the experimental study and reference to the national code,this paper proposed a calculating method of compressive strength of the recycled concrete cross-hole block wall.The work in this paper solves the strength design problem of recycled concrete transverse hole block masonry wall,and provides an important basis for the analysis of internal force and finite element analysis under vertical load.
