Abstract
The paper discusses issues concerning load tests carried out on a twin-track, arch railway bridge over the Martwa Wisla river in Gdansk. Currently, it is the bridge with the longest span in its class in Poland. The load-bearing structure consists of three no-hinge arches and an orthotropic deck suspended from them. The studies of the structure assumed the performing of static and dynamic tests. The paper presents the method for carrying out geodetic measurements during static tests as well as the analysis of obtained results. The main emphasis was on the total station measurements and precise leveling. Data was obtained concerning deck and arch displacements at controlled points and also on abutment subsidence. The tests allowed for both evaluation of the structural response under the load and verification of the safety of structure usage. The tests demonstrated that when the bridge is exposed to load, it behaves in accordance with the design assumptions and, therefore, the object can be put into operation.
