Testing and Durability of Soil-Steel Bridges
The chapter contains the durability problem of soil-steel bridges. Experimental tests of road and railway bridges under normal service loads are presented. Displacements, strains, vibration velocities, frequencies, accelerations, vibration damping in soil-steel bridges are analysed in detail. Besides, the dynamic amplification factors are also shown as the one of the most important element for designing the bridges. The load rating procedure of soil-steel bridges is presented. Durability tests of the backfill corrosivity are also described including the soil resistivity testing (Wenner method) and acidity (pH value) and moisture content of backfill. Statistical interrelation between soil resistivity and pH, moisture content was performed. American, Australian and Canadian standards concerning the estimation of soil-steel bridge durability were verified and confronted with the conditions of the minimum durability as for culverts (40 years) and the service life expected as for typical bridges (100 years). At the end of the chapter, the deformation of the ground caused by the traffic live loads is shown including the damping in soil medium. In addition, the mathematic model of soil deformation is also given.
