摘要
对36个混凝土空心砌块砌体抗剪试件(其中对比试件6个,单个孔内填夯土试件6个,两个孔内填夯土试件24个)进行了受剪力学性能试验,分析各种砌块砌体的破坏形态及破坏机理。试验结果表明:单个孔内填夯土试件和对比试件比较质量增加了42.95%,抗剪强度提高了23.91%;两个孔内填夯土试件和对比试件比较质量增加了80.16%,抗剪强度提高了50.92%;两个孔内填夯土中加竹片试件和对比试件比较质量增加了78.27%,抗剪强度提高了113.05%。
This paper presents the test results of thirty-six concrete hollow blocks under shear test, aiming at evaluating the shear strength and failure mechanism of proposed hollow blocks filled with rammed earth. The resuits showed that the mass of hollow blocks filled with single hole rammed earth increased by 42.95%, and the shear strength increased by 23.91% in comparison with contrast specimen. The mass of hollow blocks filled with two holes rammed earth increased by 80.16%, and the shear strength increased by 50.92%. The mass of hollow blocks filled with two holes rammed earth and bamboos increased by 78.27%, and the shear strength increased by 113.05%.
