摘要
由于双曲屋面结构的复杂性,采用ECOTECT软件对钛锌板屋面进行反光特性研究。首先测定钛锌板的反光系数,分析影响反射光的主要因素。采用Rhino软件对太子城站进行建模,将所建立的模型导入ECOTECT中,通过反射光线在不同时期以及不同建模参数下的变化进行反光分析。研究表明:作为屋面材料的预氧化钛锌板有较低的反射比;双曲屋面在夏季影响范围更广,在冬季影响范围较小;通过优化双曲屋面几何参数可减小反射光影响范围,降低光污染。
Because of the complexity of the hyperbolic roof structure,the reflection characteristics of the titanium zinc sheet roof are studied by ECOTECT software.Firstly,the reflection coefficient of the Titanium-zinc panels are measured,and the main factors affecting the reflection light are analyzed.Rhino software is used to model Taizicheng railway station.The model is imported into ECOTECT,and the reflection analysis is carried out by various reflected light in different periods with different modeling parameters.The results show that as a roofing material,the preoxidized Titanium-zinc panels have a low reflectivity;the hyperbolic roof has a wider influence range in summer and a smaller influence range in winter;by optimizing the geometric parameters of hyperbolic roof,the influence range of reflected light can be reduced and the light pollution can be reduced.
