Underground investigation railway section Mining, Upper Austria

Project objectives

On the ÖBB railway track 20701, within the section Mining from km 49,198 to km 57,017, an existing rehabilitation of track 1 was planned. As a basis for the planning, the geological-geotechnical underground conditions in the area of the planned renovations were to be investigated.

Project description

In order to clarify the functional status of the track ballast and to investigate the underground conditions, in particular the geological layer structure, bedding density/consistency of the existing soil and groundwater conditions, trial pits were sunk partly from the track and partly from outside the track and geologically as well as geotechnically documented. In some areas, tests were also carried out with the dynamic load plate to determine the load-bearing capacity of the subsoil in the trial pits. Due to the limited availability of track closures, some of the work had to be carried out as scheduled during night shifts.

Project data

• Total length of the remediation section: approx. 7.8 km
• Total number of trial pits: 55
