Abstract: The development and utilization of underground spaces are heavily limited by actual conditions and regulations for fire prevention. The depth of underground spaces, which is over 10 meters, cannot be applied to commercial development due to the problem of personnel emergency evacuation. This paper takes Qingdao underground civil air defense engineering as an example, in which the underground space is buried more than 10 meters depth, with contradiction between the need for crowd escape and high level of elevation difference. This example integrates elevator and stair evacuation, forming an evacuation complex, namely "body vertical evacuation". For the safety evacuation design of super deep underground space, it provides a new train of thought, and enriches the theory of safe evacuation design.

Key words: vertical evacuation body, underground space, civil defense fortifications, evacuation design

摘要： 由于自然条件、防火规范的限制，深于10m的地下空间的开发利用面临一个技术瓶颈，即受限于人员应急疏散问题而无法进行商业开发。以青岛某地下人防工程为例，为了解决埋深大于10m的地下公共空间中逃生人数多与垂直高差大的矛盾，考虑将疏散电梯与楼梯整合，形成疏散综合体，即“垂直疏散体”，旨在从建筑设计层面为超深地下公共空间的安全疏散设计提供新的思路，丰富其安全疏散设计的理论。
