逆作法单建人防工程结构设计技术

Structure Design Technology of Single Civil Air Defense Project with Top-down Construction Method

根据采用逆作法施工的单建人防工程,在结构设计过程中分别对周边围护结构、水平结构体系以及竖向支承体系等进行结构技术探讨。结果表明逆作法施工大幅减小了市中心交通繁忙的压力,减少了临街商铺的影响,缩短了工期,取得了良好的社会效果。

According to the single civil air defense project constructed by top-down method,the structural technology of surrounding enclosure structure,horizontal structure system and vertical support system in the process of structural design are discussed.The top-down construction method greatly reduces the pressure of busy traffic in the center of the city,reduces the impact of street shops,shortens the construction period,and achieves good social effects.
