摘　　要：人防地下室设置于多层地下室的底层时,人防主要出入口一般需要绕行地下一层非防护区地下室,然后利用汽车坡道出入口供战时使用。但对于这部分通道顶板的人防荷载取值规范,没有明确的规定。为此,从规范条文、人防荷载作用原理和防倒塌三个角度进行分析探讨,针对民用建筑中最常见的低级别人防地下室,给出了在不同防护等级、不同覆土厚度情况下的取值建议,并提供了其它类似情况的分析思路。When the civil air defense basement is set at the bottom of the multi-storey basement,the main entrance and exit of the civil air defense generally need to bypass the basement of the non-protected area of the underground layer,and then use the car ramp to enter and exit for wartime use.But for this part of the passage roof of the civil air defense load value standard,there is no clear regulation.Therefore,this paper analyzes and discusses from three angles of code provisions,civil air defense load principle and collapse prevention.Aiming at the most common low-level underground basement in civil buildings,it gives the value suggestions under different protection levels and different soil thickness,and provides the analysis ideas of other similar situations.
