Abstract: Based on the accurate calculation model of a suspended-pipe bridge(1) the optimization model in which a complete structure is made minimum is established in the article. The moddel is solved by discrete complex optimal method——MDCP, and the optimization design of a suspendedpipe bridge with cracks is completed.
