摘要
为了研究污泥页岩多孔砖砌体的本构关系,提出了一个待定系数的本构关系表达式,通过对砌筑的6组共36个砌体试件进行抗压试验,结合试验数据,确定了待定系数,得到本构关系表达式。通过与其它研究者提出的本构关系式对比结果表明,文中得到的本构关系式与这些本构关系式上升和下降段走势基本一致,且符合性较好,可作为反映污泥烧结页岩多孔砖砌体受压的应力-应变关系。
In order to study the constitutive relation of mud shale porous brick masonry, this paper proposed a constitutive relation expression of undetermined coefficients,based on the compression test on 6 groups of a total of 36 masonry specimens, combined with the experimental data,determined the undetermined coefficients,and got the constitutive relation expression. Com- pared with the constitutive relationship proposed by other researchers,movements in rising and falling period of the constitutive e- quation got in this paper are basically the same with that of other constitutive equation,has better compliance,can be used as stress-strain relationship reflecting the compression of sludge sintered shale porous brick masonry.
