Ying Liu

Abstract

The 2nd Zhengzhou Huanghe River Bridge proper is designed as 8×100 m simply-supported tied arch spans of concrete-filled steel tubes over the wide and braided reach in the midstream of Huanghe River. In the construction of the Bridge, the construction scheme of two-side construction trestles plus gantry cranes over piers are used. In this paper, the methods for fabrication and installation of the steel tube arches, and construction control points are described in particular.
