随着城市建设的发展和地下空间的开发利用,防空地下室设计已成工程设计的一个重要组成部分。结构设计是防空地下室设计重点,由于其设计方法复杂,设计资料和专业设计人员相对缺乏,设计人员对设计方法及概念存在模糊认识,影响到防空地下室的设计质量。从设计角度分析了防空地下室结构设计的主要特点;介绍了人防荷载的确定、荷载组合和内力分析、截面设计及主要构造规定,总结了结构设计中常见的问题和注意事项。
With the development of urban construction and the development and utilization of underground space, the design of air defense basement has become an important part of engineering design. Structural design is the key point in the design of air defense basement. Due to its complicated design method, relative lack of design data and professional designers, designers have a vague understanding of design methods and concepts and affect the design quality of air defense basements. The main features of air defense basement structure design are analyzed from the perspective of design. The identification of civil air defense load, load combination, internal force analysis, section design and main structural rules are introduced. The common problems and precautions in structural design are summarized.
