力学变形性能的研究在煤矿膏体充填材料压缩变形研究中居于十分重要的位置。通过实验室正交试验,得出了膏体充填材料的弹性模量、横向应变、纵向应变和泊松比,并首次利用数字图像测量软件绘制了材料在单轴压缩过程中的全应力-应变曲线和泊松比曲线,为选择最佳配比的充填材料提供依据。 The study of mechanical deformation performance is very important in the study of compressive deformation of the filling material of coal slurry. Through the laboratory orthogonal experiment, the elastic modulus, transverse strain, longitudinal strain and Poisson’s ratio of the paste filling material were obtained. For the first time, the full stress-strain curve of the material during the uniaxial compression was drawn by digital image measurement software And Poisson’s ratio curve, to provide the basis for choosing the best proportion of filling materials.
