摘　　要：通过深入解析相关照明设计规范,以重庆两江大桥为例,对特大型桥梁大尺度异型构件DIAlux照明模拟计算中,如何进行恰当的计算分区、并根据测试点数量推定合理的计算网格进行了介绍;提出为保证照明质量,计算中应重视被照面最不利水平线上的照度均匀度,而非被照面整体均匀度或竖向照度均匀度;指出综合运用功率密度值法、经验法、软件模拟法及现场实验法,可显著提高照明设计工作效率,并有效地减少设计值与实测数据间的误差。Through in-depth analysis of related lighting design specifications, taking Chongqing Two-river Bridge for example, the article introduced how to properly set the calculating partition and presume reasonable computational grid based on the number of test points in the DIAlux simulation computation on the large-scale special-shaped component of oversize span bridges.And it put forward that instead of overall illumination uniformity on the lighted surface or vertical illumination uniformity, the illumination uniformity of the most disadvantaged horizontal line on the lighted surface should be paid attention to during the calculation, in order to ensure the quality of lighting.And the thesis indicated that the integrated use of power density value method, empirical method, software simulation method and field experiment, could significantly improve the efficiency of lighting design, and effectively reduce the error between measured data and design value.
