Abstract
The Pizhou viaduct on Jinghang Grand Canal is a double-faces and double-towers prestressed oblique-pulling truss.Engineers applied prestress on its upper chord bars,bottom chord bars and some tension members and adopted a series of measures to ensure stress-balance of bars in every construction stage.
