TRACK FOUNDATION STRESSES UNDER VERTICAL LOADING

The article proposes a limited programme for calculating track-bed stresses against the background of the following conditions: the materials are flexible, the reactions between rail, fastenings and ballast are vertical, there is displacement continuity between the fastening and ballast, and between the ballast and track-bed, the rail has a given length and comprises between 7 and 9 fastenings. The preparation of the basic equations is accompanied by an assessment of the basic programme and a practical analysis with converging field and laboratory results.
