夜间施工补光区的确定与辅助灯优化布置研究

Determination of supplemental lighting area for night construction and optimal layout of auxiliary lamps

针对大型工程夜间照明不良影响施工工效的问题,结合施工机械干扰、照明用具数量及其照度等因素,综合运用画廊守卫定理和可见图原理初步确定了补光区辅助灯的数量和位置,接着利用移动点的可见多边形方法调整部分辅助灯位置,最终达到施工场地补光区照明的最优布置。工程实例表明,上述方法确定辅助灯布置方案的效果较好,有效降低了施工作业明暗不均匀程度,提高了施工作业工效。

Aiming at the problem that poor lighting influences the construction efficiency, and in view of various factors such as machinery interference, numbers and illumination of lighting appliances in night construction, the numbers and position of auxil-iary lamps at the supplemental lighting area were preliminarily determined with the gallery guard theory and visible graph princi-ple. Through adjusting the position of partial auxiliary lamps by the use of visible polygons of moving points, the optimum ar-rangement of supplemental lighting area was ultimately obtained. The practice shows that the method of optimal layout of auxiliary lamps in this paper obtained the satisfying results, which can effectively reduce the degree of uneven brightness in night construc-tion, and also improve the construction efficiency.
