Diagnostic and Analysis of Selected Masonry Railway Bridges on Slovak Railways

The paper presents an overview of the current state of railway masonry arch bridges that are in operation on Slovak Railways. The material of the vault is either stone or brick. It also presents the current possibilities of diagnostics, monitoring and evaluation of failures, the method of measuring selected material characteristics of masonry elements (especially the determination of compressive strength). Within the cooperation of our department and the Research and Development Institute of ŽSR, applications of diagnostic measurements and evaluation of the current state of these bridges are presented on selected bridge structures
