With the wide application of corrugated steel webs in the main beams, the first cable-stayed bridge with corrugated steel webs without backcables was born in China, Qinshihua River Bridge, which used a variety of prestressed structural systems and had the advantages of light dead weight of the main beams, good seismic performance, high prestressed efficiency and avoiding web cracking. But at the same time, it also brings some difficulties to the construction and monitoring. In this paper, combined with the construction situation of Qinshui River Bridge, some main construction techniques of superstructure are introduced respectively for the reference of similar bridge construction.
