Abstract

Recently (2007), during the rehabilitation of the Greek Railway Organization (OSE) line Korinth – Tripolis – Kalamata, longitudinal cracks have been observed in some of the prestressed monoblock sleepers of metric gauge used in this line. In this paper the methodology adopted by the committee that investigated the causes of this phenomenon is presented, e.g. on site investigation of the damaged sleepers, investigation of the probable causes of the cracks during the production of the sleepers (faulty concrete grade – faulty prestress level e.t.c.), together with theoretical considerations which, all together, led to the cracking of the sleepers.

Investigation on the Causes of Longitudinal Cracks on Prestressed Monoblock Railway Sleepers of Metric Gauge of the Greek Railway Network

Arlington, Virginia

Recently (2007), during the rehabilitation of the Greek Railway Organization (OSE) line Korinth – Tripolis – Kalamata, longitudinal cracks have been observed in some of the prestressed monoblock sleepers of metric gauge used in this line. In this paper the methodology adopted by the committee that investigated the causes of this phenomenon is presented, e.g. on site investigation of the damaged sleepers, investigation of the probable causes of the cracks during the production of the sleepers (faulty concrete grade – faulty prestress level e.t.c.), together with theoretical considerations which, all together, led to the cracking of the sleepers.
