摘要
采用砌体基本力学性能试验标准方法对不同孔型的煤矸石多孔砖砌体进行轴心受压试验,讨论煤矸石多孔砖砌体的裂缝发展特点和破坏特征。对不同孔型的煤矸石多孔砖砌体受压构件进行抗压试验,分析其抗压承载力、弹性模量及应力-应变关系。结果表明,煤矸石多孔砖砌体破坏过程和破坏特征与普通烧结砖砌体相似,但煤矸石多孔砖的承载力更高。煤矸石方孔砖砌体的承载力高于圆孔砖砌体,弹性模量试验值均高于规范计算值,按规范计算偏于安全。
The purposes of this paper are to adopt the standard for test methods of basic mechanical properties of masonry for different type coal gangue perorated brick with multiform holes masonry in axis compression test and discuss the crevice and destruction features for this masonry. We analyzed its compressive capacity, elastic modulus and stress-strain relationship though the compression test of this masonry. The experimental study showed that the failure pattern of coal gangue perorated brick masonry is similar to other experimental study on fired common perforated brick masonry,but the compressive capacity is higher. The conclusion is that the compressive capacity of the coal gangue square hole brick masonry is higher than that of the coal gangue round hole brick masonry,while the experimental value of the elastic modulus is higher than masonry structure design code computation,the elastic modulus based on the masonry structure design code of this masonry is safe.
