CONSTITUTION: A deck arch bridge structure of a long span which divides a thermal fixed point comprises arch ribs(20), long columns(31), expansion joint columns(50), short columns(61), fixed point bridge decks(30), and expansion joint bridge decks(60). The arch ribs are formed between multiple piers(10). The long columns are vertically installed in both ends of each arch rib. The expansion joint columns are vertically installed in both ends of each arch rib. The short columns are vertically installed in the center of each arch rib. The fixed point bridge decks are horizontally installed in the top end of the long columns. The expansion joint columns are horizontally installed in the top end of the short columns. |
