摘要： 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。

Abstract: The selection of model material is critical in the physical analogy of geomaterials in small scale testing. After a review of the previous research results of selecting analogy material in the small scale physical modelling of limestone, this paper presents the physical modeling results using barite powder, bentonite, paraffin oil with different material ratios. The mechanical properties of the analog material are tested and the different material components on the mechanical properties are also discussed. The optimized material components in small scale modelling of limestone are proposed.
