Abstract:

The paper presents the issue of estimating the geometry changes during construction of soil-steel composite bridges. Author presents the influence of the backfilling process on the geometry of the profile and the means to increase the upward deflection with the use of mechanical tensioning. Also the relations between horizontal and vertical deflections depending on the level of backfill are presented. Based on author’s observations, the paper will address the way to calculate the crown point upward deflection due to backfilling. Paper also elaborates on the consequences of inappropriate upward deflection during backfilling at the service stage of the corrugated structures.
