摘　　要：顶部开口半敞开式隧道采用自然通风的模式具有广阔的应用前景,为了研究它的防排烟性能,需要开展一系列试验,模拟试验是验证隧道防排烟性能的一个重要途径。为了实现顶部开口最优化分析的目的,需要使顶部开口宽度、高度、组间距、开口个数等参数易于变化。为此提出了三套模型设计方案,并分析了每套方案存在的优点及其局限性。针对1∶10缩比例半敞开式隧道模型进行了设计和优化,最终确定了模型的设计形式,并针对选择的模型设计方案提出了模型制作的选材要求,以期为后续火灾模型试验提供良好的试验平台。The tunnel with openings on roof with natural ventilation mode has broad application prospects, a series of experiments need to be carried out in order to study its smoke evacuation function, and simulation experiment is an important way to solve this problem. In order to achieve the purpose of optimization of the top openings, the top openings＇ width, height, spacing between each of the two opening groups and the number of opening groups need to be changed easily. Three sets of model design projects are presented. The advantages and limitations of each one are analyzed. The tunnel with openings on roof model is designed and optimized with 1 ： 10 proportion,and the design form of model is ultimately determined,at the same time the material selection requirements are adviced according to the model design project which is adopted,in order to provide a good experimental platform for the subsequent fire model tests.
