摘要

    摘要
  • 摘要: 以规则正六棱柱型柱状节理岩体为对象,介绍了基于3D打印技术的模拟柱状节理岩体试样制备方法,即在SolidWork中建立柱状节理网络3D打印数字模型,以光敏树脂为打印材料,采用3D打印技术打印具有不同倾角的圆柱形柱状节理网络模型,并以此为模具,采用白水泥浆为模型材料进行浇筑,经过拆模、黏结等程序制备具有不同倾角的模拟柱状节理岩体试件;再通过对试件进行单轴抗压强度试验,分析模拟柱状节理岩体试件的强度、变形和破坏特征,初步验证了上述基于3D打印技术的制样方法能够较好考虑柱状节理岩体的结构特性,反映柱状节理对岩体强度的弱化效应,所制备的柱状节理岩体试件基本满足柱状节理岩体室内试验的要求。
    Abstract: Taking regular hexagonal columnar jointed rock mass as an object, a method for preparing artificial columnar jointed rock mass specimens is proposed based on 3D printing technology. The 3D digital model for columnar joints network is firstly established by using the software Solidworks, then photopolymer resin is chosen as the printing material and cylindrical columnar joint network models with different dip angles are printed by a 3D printer. Then taking these cylindrical columnar joint network models as moulds, the artificial columnar jointed rock mass specimens are prepared following the processes of pouring white cement slurry into the mould, demoulding prisms from the cylindrical columnar joint network model and gluing the prisms. The uniaxial compression tests are performed on these artificial columnar jointed rock mass specimens, and the uniaxial compression strengths, deformations and failure properties are analyzed. Based on the above, the reliability of the proposed method was verified preliminarily. From the results, it is indicated that the structural properties and the weakening effect of columnar joints on the strength of columnar jointed rock mass are well duplicated by the proposed method, and the specimens can meet the laboratory experiment requirements well.
