Research on Underground Space Design and Construction Technology Combined with Civil Air Defense Engineering in the Context of Old City Reconstruction

Abstract

With the acceleration of urbanization in China, urban land and space resources have been compressed. The old city transformation has become a major concern in urban construction. The development and utilization of underground space provides a new development idea. The utilization of underground space in China is evolved from civil air defense engineering. Now the global situation has been relatively stable, and the utilization of civil air defense space is gradually decreasing. A major trend in the development of underground space is to transform and utilize it to meet the needs of "peacetime life and wartime air defense". Based on the combination of underground space and civil air defense engineering, this paper deals with the Xiangnan neighborhood center project in the old city block of Nanchang, Jiangxi Province, interpreting its underground space design and space construction technology, and discussing its uniqueness, so as to provide some reference for related projects.
