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.
