［提要］通過理論分析與試驗研究，分析了預(yù)應(yīng)力混凝土疊合空心板與底板開裂彎矩相關(guān)性特征，提出了二者相關(guān)性模式與相應(yīng)的計算方法，為預(yù)應(yīng)力混凝土疊合空心板與底板結(jié)構(gòu)性能檢驗提供了新的檢驗方法與計算手段，可供有關(guān)規(guī)范及標(biāo)準(zhǔn)圖集的編制和設(shè)計、生產(chǎn)、檢驗部門參考試用。
［關(guān)鍵詞］預(yù)應(yīng)力疊合空心板；開裂彎矩；相關(guān)性
Correlation and Calculation Model of Cracking Moment Between Prestressed Hollow Slab and Prestressed Concrete Laminated Hollow Slabs/Guo Legong1,2， Guo Lening3，Ｌiu Ｃhengcai2(1 Tianjin University,Tianjin 300072,China; 2 Zhengzhou University,Zhengzhou 450002,China; 3 Shanghai Normal University，Shanghai 200231, China)
Abstract:The correlation of cracking moment  between prestressed hollow slabs and  laminated hollow slabs are analysed.  The calculation models and equations about the correlation are also suggested as reference for prestressed hollow slabs and laminated hollow slabs in design, production, construction and working out of general standard gallery.
Keywords:prestressed hollow slab； laminate hollow slab；  correlation in cracking moment
