Remediation and Monitoring of Unstable Slope of Railway Cut

As part of the railway tracks modernization in Slovakia, a cut with a maximum depth of approximately 11 meters and a length of approximately 200 meters was built in the vicinity of the capital Bratislava. During the realization of the cut, in complicated engineering-geological and hydrogeological conditions, several instabilities and landslides occurred. This resulted in several remediation measures on a 200-meter long cut which were not considered in the original design proposal. After construction, geotechnical monitoring is carried out on the slope. The geotechnical monitoring aims to verify and control the effectiveness of remediation measures to maintain the safe operation of the rail transportation. This paper evaluates the results of 3-year geotechnical monitoring and analyses its relationship to the given warning level.
