摘要为解决流–固两相场隧道衬砌设计中材料模拟及参数测定的难题，开展石英砂、钢纤维为骨料，工业石蜡为黏结剂的相似材料研制，进行优化材料配比、装模温度及荷载效应测定的正交模型试验。试验表明该相似材料制备的结构模型非亲水性好、快速成型、无需养护、廉价可循环利用、制备方便，污染小、性能稳定，是一种非常适合于流–固两相场隧道衬砌的模型相似材料。在1∶100相似比试验条件下，控制装模温度在62 ℃，按石蜡∶石英砂∶钢纤维 = 15∶90∶1的基准配比，可研制出满足流–固耦合两相场隧道围岩边界条件，且破坏模式相似的衬砌相似材料。将相似衬砌应用于模型试验，通过与实际工况对比，得到合理范围的内力变化及破坏规律，满足力学参数相似原则。该相似试验的参数测定方法可为工程设计的参数对比提供选择。

Abstract：The orthogonal model tests were carried out to solve the problem of material simulation and parameter determination for tunnel lining design in the fluid-solid two phase field. The similar materials were developed by quartz sand，steel fibers and industrial paraffin，which the quartz sand and steel fibers is the aggregates and the industrial paraffin is the bonding agent. The orthogonal model test optimized the ratio of materials，the loading temperature and the load effect's measurement. The experimental results show that the structure model of the similar material has good non-hydrophilicity，rapid prototyping，no need of maintenance，low cost，convenient preparation，less pollution and stable performance. The similar material is very suitable for the tunnel lining model test in the fluid solid two-phase field. The control module temperature is 62 ℃ under the similarity ratio of 1∶100. The standard ratio will be paraffin∶quartz sand∶steel fiber = 15∶90∶1. The lining similar materials are developed to satisfy both the boundary condition of the tunnel lining surrounding rock in the fluid-solid coupled two phases field and the failure mode is similar. The similar lining is applied in the model test， and the reasonable range of internal force change and failure law is obtained by comparing with the actual working conditions，which can satisfy the similarity principle of the mechanical parameters. The parameter measurement method of the similar test can provide the choice for the parameter comparison in engineering design.
