ABSTRACT
The Gulf War of the 1990s had exerted enormous influence on people’s beliefs. Since the war ended, several countries had renewed their focus on the construction of civil air defense projects. The architectural types of civil air defense project back then were various, normally divided into two categories: single building type and attached type. To distinguish the two types, we should check whether there is solid ground building on the top of them. The one on the top of which there’s no solid ground building is the single building-type civil air defense project.
