摘　　要：通过现场调研重庆城市中心区地下街自然采光现状,从地下街安全疏散步行路径体系中的出入口、街道、中庭节点三方面开展调研,总结实例中影响自然采光条件的原因与其中存在的问题。分析现状问题对于地下街紧急时刻人们安全疏散的影响,提出基于安全疏散视角的自然采光优化改善措施,可利用主动式、被动式或两者相结合的采光法进行改善,包括增加梯段自然采光面积、增设采光天窗、引入自然采光等方面。为地下空间的安全疏散提供具有较强空间感知的自然光标识系统指引,有利于改善地下空间易迷路方向感缺失等问题,探讨总结适宜地下空间安全疏散的自然采光技术。The paper surveyed the natural lighting condition of underground streets in Chongqing urban center.The research focused on three aspects:the entrance,the street and the atrium node of the safe evacuation walking path system in the underground street.The problems of natural lighting cases,are summarised and the effect of current situation on the safety evacuation of people in the underground street analyzed.It proposed optimization methods on safety evacuation perspective of natural lighting.and could be improved by active lighting technology,passive lighting technology or both.It included increasing the natural lighting area of ladders,adding lighting skylights and introducing natural lighting.These measures will provide strong spatial awareness guidance for the safety evacuation of underground space with a natural light identification system.It will be helpful both in improving the problem of the lack of directional sense in the underground space,and in exploring the natural lighting technology for safety evacuation in underground space.
