摘　　要：下沉式建筑能够有效利用地下空间提升土地利用率,同时规避地下建筑通风不良、采光不足等问题,具有重要的开发意义和应用价值。本文提出一种基于正交试验优化下沉式建筑底层通风和采光的方法。该方法运用数值模拟工具计算下沉式庭院的通风、采光指标值,针对下沉式建筑的设计要素(如:下沉深度、下沉宽度、底层窗台高度、楼层数),基于正交试验方法,分析各要素影响下沉式建筑底层风环境、光环境的主次顺序和规律,并对各设计要素的取值进行优化决策,得到使下沉式建筑底层通风、采光综合最优的方案。该方法可以为下沉式建筑的初期方案设计提供参考。The sunken architecture can raise the land-use capability without the defects of poor natural ventilation and inadequate daylighting of conventional underground buildings. So it has great development significance and application value. An optimization method based on orthogonal experiment was proposed for the ventilation and daylighting of the sunken architecture. The average indoor pressure differential and daylight factor of the sunken architecture were calculated by numerical simulation. The impact order and rule of the architecture design factors ( the sunken height,the sunken width,the windowsill height and the number of floors) on the natural ventilation and daylighting of the sunken architecture were analyzed based on orthogonal experiment. The optimized combination values of the architecture design factors were obtained with good natural ventilation and sufficient daylighting. The method can provide easy and effective way for the schematic design of the sunken architecture.
