Construction control of outside the steel arch centre of RC arch bridge;

Sectional Optimization and Procedures on Steel Truss Arch Structure;

The main part of Yaojiang Bridge at Chengzhuang Rd, Ningbo is a continuous 3-span (48 m+180 m+48 m) through steel truss arch bridge, and introduced hereby are the layout of the bridge, the structural design, some key design techniques and the guiding sequence of construction.

It introduces the supporting method of "advanced anchor shaft combined with reinforcement centering spraying concrete" in Qingdao "902" Project, which achieved good effect under the complicated geographic condition characterized by broken rock and thin covering layer and thus accumulated successful experience.

By considering of the structural deformation, the span of the vaulted tubular steel space truss in Nanjing International Exhibition Center is designed and manufactured as 74.
