对地铁车辆基地上盖超大规模合成建筑,提出“板地”概念,将“板地”作为上盖建筑的安全疏散救援场地,加强对“板地”结构的防火构造。上盖综合开发与车辆基地的防火分类、防火设计应以“板地”为界定区域,消防各自独立设置。解决大尺度空中平台“板地”一体的防火设计难题,提供行之有效的实施措施和设计依据。 On the metro car base super large-scale composite building, proposed “plate ” concept, “plate ” as a safe evacuation site for the superstructure, to strengthen “plate ” structure of the fire protection structure. Comprehensive development of the superstructure and fire classification of the vehicle base, fire protection design should be “plate ” for the definition of the region, the fire were set up independently. Solve the large-scale air platform “plate ” fire design problems, to provide effective implementation of measures and design basis.
