［摘要］贛州西站主站房高架候車層具有跨度大、預(yù)應(yīng)力體量大、梁柱節(jié)點核心區(qū)密集等特點，采用緩粘結(jié)預(yù)應(yīng)力技術(shù)。對超長結(jié)構(gòu)樓板溫度效應(yīng)以及結(jié)構(gòu)大跨梁受力進行整體分析計算，同時利用有限元軟件計算模擬，總結(jié)緩粘結(jié)預(yù)應(yīng)力在超長結(jié)構(gòu)混凝土板、梁的設(shè)計方法及施工驗算，結(jié)果表明：1）計算溫度效應(yīng)對結(jié)構(gòu)樓板帶來的影響時，需綜合考慮樓層高度，并考慮豎向構(gòu)件對樓板的約束作用，樓層越高，豎向約束作用越小，樓板溫度應(yīng)力釋放越多；2）緩粘結(jié)預(yù)應(yīng)力筋適合運用在大跨公共建筑中，特別是在后期改造和密集節(jié)點核心區(qū)的穿行處理上具有優(yōu)勢。

Abstract:The elevated waiting layer for the main station building of Ganzhou West Railway Station has the characteristics of large span, large prestress, and dense core area of beam-column joints. It adopts slowly-bonded prestressed technology. The overall analysis and calculation of the temperature effect of the super-long structure floor and the stress of the large-span beams of the structure were carried out. At the same time, the finite element software was used to calculate and simulate. The design methods and construction calculations of slowly-bonded prestressed concrete slabs and beams in super-long structures were summarized. The results show that: 1) When calculating the effect of temperature effects on structural floors, the floor height and constraints of vertical members on floors need to be considered comprehensively, and the vertical restraint and the thermal stress release of the floor are in positive proportion to the floor height; 2) the slowly-bonded prestressed tendons are suitable for use in large-span public buildings, especially for the later stage transformation and handling the passage of the dense joint core area.
Keywords:super-long structure; temperature effect; slowly-bonded prestressed structure; combination of station building and bridge
