Concrete bridge deck slab anti-cracking structure and method in midspan area of steel-concrete composite beam cable-stayed bridge
The invention provides a steel-concrete composite beam cable-stayed bridge midspan area concrete bridge deck anti-crack structure which comprises a steel main beam and a concrete bridge deck located on the steel main beam, and the concrete bridge deck comprises non-midspan area concrete bridge decks located at the two ends of a cable-stayed bridge and a midspan area concrete bridge deck located in the middle of the cable-stayed bridge. A bridge deck breaking joint is arranged between the midspan area concrete bridge deck and the non-midspan area concrete bridge deck. The steel main beam and the concrete bridge deck are connected through shear nails, the shear nails between the steel main beam and the concrete bridge deck in the non-midspan area are densely arranged, and the shear nails between the steel main beam and the concrete bridge deck in the midspan area are sparsely arranged. The invention further provides an anti-cracking method for the concrete bridge deck slab in the midspan area of the steel-concrete composite beam cable-stayed bridge.
本发明提供一种钢混结合梁斜拉桥跨中区域混凝土桥面板抗裂结构，包括钢主梁、位于钢主梁上的砼桥面板，所述砼桥面板包括位于斜拉桥两端的非跨中区域砼桥面板、位于斜拉桥中部的跨中区域砼桥面板，所述跨中区域砼桥面板与所述非跨中区域砼桥面板间设有桥面板断缝。所述钢主梁和砼桥面板之间采用剪力钉连接，所述钢主梁与所述非跨中区域砼桥面板间的剪力钉布置密集，所述钢主梁与所述跨中区域砼桥面板间的剪力钉布置稀疏。本发明还提供一种钢混结合梁斜拉桥跨中区域混凝土桥面板抗裂方法。
