摘要
地下中庭式站点是从单纯的交通功能空间逐渐转向具有新颖空间体系、独特引导效果、巨大发展潜力的新型交通空间,与周边地下空间具有相互关联的高效性与便捷性。文章对功能高度集成的岗厦北枢纽的疏散难点进行分析,针对中庭式枢纽的特殊空间形式及火灾特点,在部分消防设计难以满足现有规范的前提下,提出在防火防烟分区划分、消防疏散、防排烟系统配置等方面的优化解决方案。
The underground atrium site is gradually shifted from a simple traffic function space to a novel space system with unique guiding effect and great development potential.The new transportation space has the efficiency and convenience associated with the surrounding underground space.This paper analyzes the evacuation difficulties brought by the highly functional Gangxia North Hub.According to the special space form and fire characteristics of the atrium hub,under the premise that some fire protection designs are difficult to meet the existing specifications,this paper proposes to build fire and smoke prevention zones and optimize the solutions of the division,fire evacuation,and the configuration of smoke control systems.
