摘　　要：将天然光高效引入地下空间,对于营造舒适健康的光环境和为建筑节能降耗有着重要意义,而当前量化地上建筑的遮蔽影响并将其融入地下采光设计的研究不足。文章基于地下空间采光界面全年总太阳辐射的分布状况,优化天窗位置与间距,通过比较分析不同方案的采光效果,结果发现:优化方案的采光效果较均布方案更好;总开窗面积相同时,随着天窗数量的增加,地下空间的有效采光面积呈现先增加后减少的趋势。The efficient import of daylight into the underground is of great significance for creating a comfortable and healthy light environment and reducing energy consumption in buildings,but there is insufficient research on the shading effect of the above-ground buildings and their integration into underground daylighting design.Based on the distribution of annual total solar radiation at the daylighting interface of the underground space,this paper optimizes the location and spacing of skylights,and by comparing and analyzing the daylighting effects of different schemes,it is found that:the daylighting effect of the optimized scheme is better than that of the uniform scheme;when the total skylight area is the same,with the increase of the number of skylights,the effective lighting area of the underground space increases first and then decreases.
