Study on Transverse Block Pouring Construction of Super-wide Concrete Bridge Deck
Super-wide concrete bridge deck is one of the key parts in bridge engineering,and its transverse block pouring construction is the key factor to improve the quality of bridge deck.Combined with a super-wide bridge with a width of 61.7 m,Midas FEA finite element software is used to establish the transverse block pouring construction model of the concrete bridge deck.Four construction schemes of transverse 2-block pouring,transverse 4-block pouring from outside to inside,transverse 6-block pouring from outside to inside,and transverse 6-block pouring firstly from the most outside,then to the most inside and finally to the middle block are calculated and compared respectively.The best construction method achieved is the half-width transverse 4-block pouring from outside to inside,which is consistent with the construction method adopted in the actual site construction.
