The problem of the arch barrel deformation in railway backfilled arch bridges caused by their typical service loads is analyzed. The main attention is paid to vertical or radial displacements of the characteristic points of the arch barrel. In the study, results of deflection measurements carried out on single- and multi-span backfilled arch bridges during passages of various railway vehicles are used. On the basis of such results empirical influence functions of displacements are being created. In the next step, the results are utilized to estimate bending effects within the arch.
The paper includes different solutions based on measurements of displacements in various points and directions for cases of single as well as multi-span bridges. It presents a potential of the proposed methodology as an effective tool of comprehensive calibration of numerical models of such bridges on the basic of field tests carried out under any live loads. This method may comprise an important element of multi-step assessment procedures for masonry arch bridges.
