石家庄六线隧道模型试验相似材料研究

满足相似关系的模型材料是模型试验成功的关键。在调研相似材料研究现状的基础上，依托石家庄六线隧道模型试验项目，应用量纲分析法推导出了相关参数的相似判据。根据相似原则，以粘聚力和摩擦角为主要相似判据，选用重晶石粉、石英砂和凡士林的混合物为模型材料，通过正交设计法研制出了地层相似材料。以抗压强度为相似判据，选用石膏材料为模型材料，研制出了灌注桩和锚索注浆体相似材料。

Research on Analogous Material of Model Test for Six Line Tunnel in Shijiazhuang

Model material which satisfies the similarity criteria is the key to the success of model test.On the basis of investigation of the research status of analogous material,depending on model test of Shijiazhuang six line tunnel,the similarity criterion of corresponding parameters is derived by dimensional analysis method.According to the principle of similarity,adopting cohesion and friction angle as main similarity criterion,taking the mixture of barite powders,quartz sand and Vaseline as model material,a st...
