重庆机场指廊超长预应力结构设计与施工

Design and Construction of Ultra-long Prestressed Structure of Corridor of Chongqing Airport

重庆国际机场航站楼候机指廊工程预应力混凝土超长结构设计中,综合考虑了各方面因素;施工中采用分段张拉和分散搭接等措施,获得了较大的有效预应力,分散了局部预压应力。

In the design of the ultralong prestressed concrete structure of the waiting corridor project of airport buildings of Chongqing International Airport, engineers comprehensively considered all factors. In construction, they adopted segment pulling and discrete overlapping to obtain larger effective prestress than other methods, and to disperse local precompressionstress.
