Construction Control Technology of Cable Hoisting System for the Arch Rib of Steel Box Bridge

Article Preview

Abstract:

Mingzhou bridge in Ningbo is a half-through steel box arch bridge with 450m main-span. The bridge adopts welded steel structures except that abutments are made of steel composite structure. High requirements for the bridge construction technology are put forward because of the restrictions including poor geological conditions for bridge site, height limit for aircraft, narrow channel, frequent typhoon. The mid-span arch rib adopts cable hoisting and stayed buckle cable technology for the construction. This paper introduces the construction method during the assembled process of the mid-span arch rib. The numerical simulation analysis for the construction process is carried out. Stress and deformation of the main arch are in a reasonable range, which indicates completing the bridge construction control target successfully.
