摘要
基于正交设计方法,将雅沪高速公路某隧道围岩的粘聚力和摩擦角作为研究目标,使用粉煤灰、干河沙和机油作为原料进行拌和,较好地模拟了V级围岩。通过大量试验,确定相似材料物理参数的影响因素并进行敏感性分析,最终确定材料的合理配比,为下一步的试验研究做好准备。
Depending on orthogonal design and taking cohesive strength and friction angle of the surrounding rock at certain tunnel along Ya'an-Lugu Highway as the research object, fly ash, dry river sand and machine oil are used as raw materials and mixed to simulate Class V surrounding rock. Through numerous experiments, the factors affecting the physical parameters of the similar materials are defined and, with sensitivity analysis, a proper proportion of the materials is specified finally and to be ready for the next test study.
