Inspection and load tests on viaducts on the Madrid - Saragossa - Barcelona - French Border highspeed railway line

Performance of the main inspections and static and dynamic load tests for reception of the railway structures on the Lleida - Vilafranca del Penedés section
Sector Urban Works (Instrumentation and monitoring)
CountrySpain (Europe)

Description

From the main inspections carried out, the corresponding technical documentation for integration of the structures in ADIF's Infrastructure Management System was generated. Specifically, the sheets for the Ministry of Development's Register of Bridges (ITPF-05) and the control sheets identifying the bridges' “Zero Status” before being put into service were completed.

After preparation of the static and dynamic load test project plans by Control and Instrumentation Engineering's technical office, the tests were carried out on railway material supplied by ADIF. This meant the static tests included in these plans and dynamic tests at different speeds, with sampling of up to 1000 samples per second at all control points installed: measurement of deflection, unit deformation and acceleration.

Activity

  • Collection of Project Design and Construction Information.
  • Main Inspection of Structures
  • Design of static and dynamic load test plans, with structure modelling using programs of finite elements.
  • Performance of load tests in the field
  • Preparation of the Final Technical Decision on the functional condition of each structure/bridge.
