摘　　要：通过模拟玻璃幕墙建筑建立三维空间模型,研究不同日期、时间以及玻璃幕墙方位的反射光影响程度和影响范围,总结玻璃幕墙反射眩光的一般特征。结果表明:冬至时反射眩光影响(“轻微影响”和“强影响”)时长要大于春秋分和夏至日,最大时长达5.2 h;控制玻璃幕墙反射率小于7%时,反射光影响均可接受,无眩光影响;当玻璃幕墙建筑正向分布时(四个立面朝正东、西、南和北)时反射眩光影响范围集中在东侧和西侧,随着建筑物旋转其玻璃幕墙反射眩光影响范围跟着转移,当建筑物旋转到45°时,反射眩光影响范围集中在北侧和南侧。该研究可为建筑玻璃幕墙建设、设计及光污染评价提供参考。This paper establishes a three-dimensional space model by simulating glass curtain wall buildings,studies the influence degree and range of reflected light at different dates,times,and orientations of glass curtain walls,and summarizes the general characteristics of reflected glare from glass curtain walls.The results show that the reflection glare effect(“slight effect”and“strong effect”)during the winter solstice is longer than the spring and autumn equinox and summer solstice,and the maximum is 5.2 h.When the reflection rate of the glass curtain wall is less than 7%,the reflected light effects are all acceptable,no glare effect;when the glass curtain wall building is distributed in a forward direction(the four facades are facing east,west,south,and north),the reflection glare influence range is concentrated on the east and west sides,as the building rotates its glass The influence range of the reflection glare of the curtain wall is shifted.When the building is rotated to 45°,the influence range of the reflection glare is concentrated on the north and south sides.The research can provide a positive reference for the construction,design and light pollution evaluation of architectural glass curtain walls.
