| 摘 要： | 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。

| Abstract: | Research of mechanical deformation properties is at a very important position in mine paste filling material compression deformation research.Through laboratory orthogonal test,elastic modulus,horizontal strain,vertical strain and poisson's ratio of paste filling material are gotten.For the first time through digital image measurement software,complete stress-strain curve and poisson's ratio curve of which paste filling material is in the unidirectional compression process are drawn.All those provide the ba... |
