Abstract

To get informations about the deformation and bearing behaviour of a soil improvement by the use of Lime-Cement Columns under a railway line on soft soil large scale field tests were performed. The tests were observed by various static and dynamic measurement devices and over a period of 3 months 1200 train crossings were recorded. During the test stage the train speed varies from 30 km/h to 90 km/h to analyse the influence of the train speed on the dynamic behaviour and the stabilizing effect of the soil improvement. The measurements show that the large and heavy goods trains are crucial for the maximum dynamic response of the soft soil. The best results were achieved if the Lime-Cement Columns are founded in the good bearing sand layer.

Soil Improvement of Soft Soil Under Dynamic and Static Loading — Case History of a Geotechnical Field Experiment Under a Railway Line
