Abstract
The main bridge of Pizhou Viaduct across the Beijing Hangzhou Canal is a continued presstressed concrete beam structure with double pylons,double slantingly tensioned plane trusses.The construction is divided into several sections and steps of pouring and prestressing.The construction procedures are complicated,the structure systems and forces in the members are varied during the construction.The monitoring results are introduced and the main truss structure of the main bridge are analyzed.
