GROUND PRESSURE MEASUREMENTS DURING HIGH-SPEED TRIALS BETWEEN GUETERSLOH AND NEUBECKUM

The results of the ground pressure measurements performed by Deutsche Bundesbahn in connection with the high-speed trials between Gutersloh and Neubeckum may be summarised as follows: Each wheelset or, in case of a concrete-slab permanent way, each bogie causes a pressure peak when running over the load cells. With ballast permanent ways, the vertical pressures rise with the speed, this effect being less pronounced in case of the horizontal ground pressures, The vertical ground pressures measured are below 10 N/sq cm for a Series 103 electric locomotive (axle load 19.5 tonnes), the scatter being comparatively large. In the upper range of wooden sleeper installations the ground pressures are slightly higher than below concrete sleepers. From a depth of 120 cm, both types of sleepers render comparable ground pressures. With concrete-slab permanent ways, the ground pressures vary only slightly and are considerably smaller than below ballast beds. The vertical pressures measured are below 3 N/sq cm for a Series 103 electric locomotive (axle load 19.5 tonnes), the scatter being comparatively small. Judging by the test results, it may be anticipated that the requirements in respect of the bed and the formation line as laid down in DB's earthwork engineering rules for new lines will ensure an unobjectionable operation.
