在总结灰岩相似材料特性研究现状的基础上,借鉴前人的经验,通过大量的配比试验,利用重晶石粉、膨润土、石蜡油为主要材料,对小比尺模型试验中灰岩特性进行了模拟,对其力学特性进行了测试,并且探讨了各材料含量对相似材料试件力学性质指标的影响。材料的力学试验表明,提出的相似材料配比范围,试验得出的力学参数范围及破坏特征符合实际,证明该相似配比范围满足小比尺模型试验的要求,具有一定的借鉴意义。
On the basis of summarizing the research status of the similar materials of limestone, based on the experience of the predecessors, through a large amount of proportioning experiments, the characteristics of the limestone in the small scale model test were studied using barite powder, bentonite and paraffin oil as the main materials The simulation was carried out, the mechanical properties of the material were tested, and the influence of each material content on the mechanical property index of similar material specimens was also discussed. The mechanical tests of the materials show that the proposed range of similar materials, the range of mechanical parameters and the failure characteristics obtained by the experiment are in line with the actual conditions, which proves that the scope of the similar ratio satisfies the requirements of the model test of small scale, and has certain reference value.
