【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。更多还原

【Abstract】 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.更多还原
