In the process of long-span multi-segment continuous curved steel-box girder bridge constructed by incremental launching method,how to adjust the height of temporary piers to insure the safety of steel-box girders and temporary piers is a complex problem.

This paper has made introduction of construction technology of steel box continuous curved beam as the references for construction departent and design department.

A corresponding program was designed to calculate the shear lag of continuous curved box girders.

Analysis of spatial responses of continuous curved box girder bridges under action of live loads;
