摘　　要：采用数值模拟的方法对天津某交通枢纽地下空间的自然采光情况进行了分析与优化研究.通过模拟结果可知,其候车大厅自然采光效果较好,春秋分、夏至、冬至照度平均值分别为3,620.64,4,497.60,2,178.97,lx;站台层春秋分、夏至、冬至照度平均值分别为34.97,43.79,21.10,lx;进站厅下方扶梯秋分日照度平均值为99.29,lx.经采光设计优化后,站台层照度平均值提高了约40%,,分别达到51.7,64.86,31.28,lx;进站厅下方扶梯照度平均值提高了110.9%,,达到209.42,lx.In this paper, the daylight of an underground transportation hub in Tianjin is studied by using the method of numerical simulation. It can be seen from the numerical simulation results that the average illumination in the waiting halls is3,620.64, 4,497.60 and 2,178.97 lx in the equinox, summer solstice and winter solstice respectively, while that of the platform layer is 34.97, 43.79 and 21.10 lx. By optimizing the original daylight design of the platform, the average illumination has increased 40% and reached 51.7, 64.86 and 31.28 lx. The average illumination of the escalator below pitted hall is 99.29 lx.By optimizing the design, the average illumination has reached 209.42 lx.
