摘要

This paper presents a survey of construction techniques for pre-stressed concrete (PC) box-girder bridge with corrugated steel webs in recent decades. The structural forms of the bridge have experienced simply supported beam bridge, continuous girder bridge, cable-stayed bridge and the continuous rigid frame bridge. Meanwhile, the construction technologies were constantly innovated, including cast-in-situ, precast and the combination of them. The processing and installation technologies of corrugated steel webs and several typical construction techniques for PC box-girder with corrugated steel webs were elaborated, such as full framing construction, cantilever construction, span-by-span construction, incremental launching construction and some other various innovative ways. The valuable experiences in a variety of construction methods were summed up. The results show that some innovative construction ways should be developed by fully utilizing the corrugated steel webs as a guide beam or a work platform to improve the efficiency of construction.
