The way in which a new road bridge made from Super Cor corrugated steel plates was tested during the three stages of its construction is described and the test results are presented. In construction stage I, the bridge was loaded with backfill and in stages II and III, with two ballasting vehicles. The box bridge spans the Bystrzyca Dusznicka River in Polanica Zdrój (Poland). The span’s effective length is 12.27 m and its vertical inside diameter is 3.85 m. The steel span is founded on two reinforced concrete strip foundations. The average values of the displacements and strains (normal stresses) measured in selected points and on selected elements of the steel shell structure were much smaller than the ones computed for the same load. The conclusions drawn from this research can be helpful in determining the interaction between the steel shell and the backfill. Since this type of steel-soil structures are increasingly widely used in Poland and in the world, the conclusions can be extended to a whole class of similar bridge designs.

Przedstawiono sposób przetestowania nowego mostu drogowego wykonanego ze stalowych blach falistych typu Super Cor i zaprezentowano wyniki otrzymane trzech etapach budowy. W I etapie badań obciąSenie stanowiła zasypka gruntowa, a w II i III etapie – dwa pojazdy balastujące. Badany most o podatnej konstrukcji „skrzynkowej” jest połoSony nad rzeką Bystrzycą Dusznicką w Polanicy Zdroju. Rozpiętość teoretyczna przęsła nowego mostu wynosi 12,270 m, a jego światło pionowe – 3,85 m. Przęsło stalowe jest posadowione na dwóch Selbetowych ławach fundamentowych. Maksymalne wartości pomierzonych przemieszczeń i odkształceń jednostkowych (napręSeń normalnych) w wybranych punktach i przekrojach stalowej konstrukcji powłoki były stosunkowo małe i wywołane tym samym znanym obciąSeniem. Wnioski z przeprowadzonych badań mogą być przydatne w określeniu współpracy powłoki stalowej z gruntem zasypowym. W Polsce i na świecie coraz częściej stosuje się tego typu konstrukcje stalowo-gruntowe do budowy małych i średnich mostów połoSonych w ciągu linii drogowych i kolejowych, dlatego wnioski z badań przeprowadzonych w trzech etapach budowy, moSna uogólnić na całą klasę podobnych rozwiązań konstrukcyjnych.
