- Abstract
- Hangzhou Jiubao Bridge crosses the Qiantang River with full length of 1855 m, which is the first large river crossing project completely using composite structure in China. The main navigation span, of span arrangement of 3x210 m, uses the continuous hybrid arch-girder structure, with multi-point simultaneously incremental launching construction method. The design scheme comes out an integrated consideration of both structure and construction technology. For the purpose of safe, reliable, efficient and economical construction, tracked incremental launching equipment is especially developed with only one temporary pier considered for the 210 m main arch span during the launching construction. Design scheme of this bridge presents new design philosophy, technology and creativity.
